Jeep AC blows warm? (Professionals recommend)

  • This may be caused by a weld issue inside the service port on the liquid side. This condition is difficult to diagnose since the A/C gauge set (when connected) will cover-up the leak point. Chrysler has determined that the leak causing the Jeep AC blows warm condition is located inside the liquid line service port.

Why is my Jeep AC blowing warm air?

An A/C blowing hot air has several possible root causes. There could be an issue with your compressor clutch, a blown fuse, a leak, or a clog in the expansion valve.

Why is my car AC blowing warm air?

The most common cause of an AC system blowing warm air is a lack of refrigerant, though, you may also have a problem with your condenser. Other possibilities include a faulty compressor, broken cooling fans, or an issue in your electrical system.

Why is my AC blowing but not cold?

If your central AC is not blowing cold air, the refrigerant may be the problem. The unit could be running low and need additional refrigerant added. The most likely cause of this is a leak. If you suspect a refrigerant leak, you should contact an HVAC professional right away.

What does it mean when your AC blows hot?

When AC is blowing warm air, the most common cause are low freon levels. Due to the lack of freon, there the freon expansion (turning it from liquid to gas) is not sufficient. That means the cooling coil will not be adequately cooled; in fact, it might start to become warmer the longer we run the AC.

How do I know if my car AC compressor is bad?

What Are the Signs and Symptoms of a Bad A/C Compressor?

  1. A Lack of Hot Air Being Released Outside.
  2. Loud or Strange Noises From the Unit.
  3. Failure of the Compressor to Turn On.
  4. Circuit Breaker Tripping.
  5. Leaks Around the Air Conditioning Unit.
  6. Warm Air Instead of Cool Air Being Delivered to the House.
  7. Reduced Airflow.

How much does it cost to fix refrigerant leak in car?

If leaks are detected, it typically costs $150-$800 for minor repairs to a vehicle’s air conditioning system and then recharging it. This generally includes replacing a few parts like hoses, sensors, or either the compressor or condenser.

How do I fix my AC from blowing hot air?

If your AC is blowing hot air, the thermostat may have been accidentally set to “heat.” If this is the case, it’s easy to fix on your own. Simply flip the thermostat setting back to “cool” and see if the air conditioner begins to blow cool air again.

Why does my car AC not work when it’s hot outside?

The hotter it is outside, the harder the air conditioning in your vehicle has to work. Rising outside temperatures put extra strain on your entire vehicle and its cooling system, from the battery and belts to hoses and fluids, requiring each part to work overtime to keep your vehicle cool.

How do I fix my car air conditioner that is not cooling?

The most common cause of a vehicle’s air conditioner not getting cold enough is that it needs to be recharged. You can recharge your refrigerant by yourself, but to save time and make sure the job is done correctly you should make an appointment with your local professional auto shop.

Should I turn off AC if it’s not cooling?

If your ac is still not cooling there is one more thing you need to do. This is very important. TURN IT OFF and call your HVAC service provider to assist you. We always tell our customers to turn off an ac that is not cooling properly.

Why would AC work but not heat?

A Faulty Thermostat Try turning on the thermostat and adjusting the temperature so that your HVAC is turned on. If it fails to come on, check the circuit breaker and ensure that the switch is functioning properly. If you find that it had tripped, turn it back on. This should fix the problem.

Why is My Car’s Air Conditioning Blowing Warm Air?

When it’s operating properly, your air conditioner is fantastic. In the absence of a working air conditioner, traveling in your automobile can be difficult, particularly on hot summer days. If your air conditioner is blowing warm or even hot air, there are a few possibilities as to why this can be happening. Here are a few of the most often cited reasons. Problems with the electrical system First and foremost, it is possible that your electrical system is experiencing difficulties. The cabling, switches, fuses, relays, and other components of the electrical system are responsible for delivering electricity to the air conditioning unit and are intended to shut down if even a single component fails.

Fortunately, this is rare.

Change The Cabin Air Filter is an important piece of equipment.

Cabin air filters are capable of capturing dust, bugs, leaves, and a variety of other forms of material.

  • Failure of the compressor It is also possible that your compressor has failed, which is a typical occurrence.
  • Because it is one of the most critical components of an air conditioning unit, a compressor failure can result in the complete failure of the system.
  • If you have a leak in your system, it might be causing your unit to blast warm air since there isn’t enough refrigerant in the system to cool things down.
  • The pros at your local auto shop utilize sophisticated gear, like as ultraviolet detectors, to determine whether or not your system has developed a leak.
  • As a result, because the condenser is placed nearer to the front of the car, it is more susceptible to damage from road debris such as fallen leaves or plastic bags, as well as pebbles and sticks, which can create punctures.
  • However, if it fails to do so, or if it does so inefficiently, the refrigerant will remain warm and will be unable to chill the air beyond the temperature of the surrounding environment.

Whenever this condenser malfunctions or is somehow compromised, your air conditioner will produce heated air. To get assistance in staying cool and comfortable this summer, schedule an appointment to have your car evaluated by one of our experienced air conditioning technicians.

Why is My Car AC Blowing Hot Air?

It might be a rude awakening to find yourself in your automobile after a beautiful spring day in the sun. When your car is left in direct sunshine, the glass and interior of the vehicle behave very much like a greenhouse. The sun’s energy can enter your home through your windows or be absorbed by your metal roof, but it has no ability to leave through any other means. It is possible that on bright days, the trapped heat will cause the interior of your car to become quite hot. You may assist moderate this impact by tinting your windows, painting your car a light color, or employing a windshield sunshade, but even these are not answers; they only serve to significantly diminish the burn scars on the backs of your thighs caused by your heated leather seats on long journeys.

Of course, it takes a few seconds for the air to cool down, but what if you’ve been driving for a minute or two and your car’s air conditioner is still pumping hot air in your direction?

“Why is my AC blowing hot air?” Check These Common Causes:

  • Broken cooling fans
  • Broken condenser
  • Low refrigerant owing to a leak
  • Electrical failures
  • Blocked condenser

The condenser in your car’s air conditioning system has a similar appearance to a radiator and is located at the front of the vehicle. It is utilized to cool the hot compressed refrigerant back down to ambient temperature when it exits your compressor, and it does so by utilizing the air that your vehicle is passing through. It is necessary to achieve this because otherwise, the refrigerant would still be hot when it passes through the expansion valve. If this is the case, the heated refrigerant will only be cooled back down to ambient temperature, preventing your air conditioner from functioning.

  1. A simple visual check of the condenser via your grill will help you determine whether or not it is clogged with debris.
  2. The fans might be physically damaged, such as by a burned-out motor, a defective mount, or a chipped fan blade, or they could simply be experiencing an electrical problem, such as a blown fuse or a burned-out relay.
  3. If the puncture is substantial and clearly visible, it is probable that replacement is your best option.
  4. Similar to this, you may have low refrigerant levels owing to a variety of different factors such as weak connections, outdated hoses, or the simple leakage of refrigerant with time.
  5. Check your air conditioning system before you recharge it with new refrigerant to make sure it is properly sealed and will contain the new refrigerant.
  6. It is possible for a typically functioning system to stop working merely because of a defective connection or a malfunctioning sensor, for example, due to broken condenser fans or an electrical failure.
  7. Read our article on diagnosing electrical problems for more information on tracking down electrical issues like this.

Take a look at this video from AC Avalanche to see how the air conditioning system of a car works. Several issues with automobile air conditioning systems are caused by leaks, which are quite simple to repair. Clogged tubes and failing air conditioning blower motors are both possible causes of the problem.

5 Common Problems with the Jeep Cherokee Air Conditioning System

Jeep Cherokee Limited (2016 model year)

1. Faulty Cooling Fans

Some Jeep Cherokee customers have complained that the air conditioning system does not blow air adequately. This is frequently caused by a malfunctioning cooling fan. A mechanic can do an inspection of the air conditioning system and replace the cooling fan if the problem persists.

2. AC Settings Continually Reset

Some Jeep Cherokee drivers have reported that the air conditioning settings on their vehicles have been reset at random. For the majority of drivers, this is just a nuisance. A technician may do an inspection of the air conditioning and electrical systems, as well as replace any malfunctioning components. 11286884 is the National Highway Traffic Safety Administration’s (NHTSA) complaint identification number for this issue.

3. AC System Interacts Inappropriately with Electrical Components

It has been claimed by certain Cherokee owners that when the air conditioning is turned on, electrical parts of the car fail to function properly. Some customers have complained that all of the gears on the shifter light up at the same time, while others have complained that the vehicle’s infotainment system is not working properly. While this problem may be only an irritation, the combination of the two faults may be distracting. When a motorist is distracted, he or she may lose concentration on the road, increasing the probability of a collision.

Complaint ID 11208641 has been assigned to this issue by the NHTSA.

4. Air Conditioning Suction/ Discharge Hose May Split

When this problem occurs, the car’s air conditioning may suddenly stop working while the vehicle is in motion. Despite the fact that Jeep issued a recall for some of the vehicles that were affected by this problem, some vehicle owners whose VIN was not included in the recall have also reported experiencing the problem.

In order to resolve this issue, your mechanic will need to examine the air conditioning system and, if required, replace the suction/discharge hose. The complaint number assigned by the NHTSA is 11207299.

5. Mold Odor Coming from AC System

When the air conditioning or heating components of the Jeep Cherokee are turned on, some Jeep Cherokee owners have reported smelling mildew coming from the HVAC system. While this is unlikely to represent a safety concern, it is an unappealing condition that needs to be addressed immediately. A mechanic can disassemble the air conditioning system and identify the cause of the odor in order to resolve the issue. The complaint number assigned by the NHTSA is 10926205.

Frequently Asked Questions

20th of September, 2021

Why is my Jeep Cherokee AC not working?

Make sure that there are no electrical problems with your Jeep Cherokee’s air conditioning system before proceeding with the rest of the troubleshooting steps. These are the simplest to repair since you can typically correct the electrical faults by resetting the A/C settings on the dash or by removing and replacing the fuse in most cases. If there are no electrical issues, the next thing to look for is a refrigerant leak in the A/C system, which should be checked immediately. It is possible to detect a leak by checking the refrigerant lines with a meter to verify if they are correctly charged.

The last thing you should look for is a malfunctioning air conditioning compressor.

As a result, the air conditioning blows heated air.

What would cause my car air conditioner to stop working suddenly?

If the air conditioning in your Jeep Cherokee suddenly stops working, the first thing I would recommend checking is the fuses for the A/C system and the fans. If one of them has blown, the fans will not operate, and you will not receive any airflow from your air conditioning system. These are also the simplest to repair because, in most cases, all that is required is a new fuse to restore functionality to your machine. An additional item to look for if your air conditioning system suddenly stops working is the auxiliary drive belt.

In most cases, one of these two items is the source of the problem in a Jeep Cherokee; for example, if there are leaks or the compressor is malfunctioning, you will observe a progressive drop in cooling performance rather than it suddenly ceasing to function completely.

How do you turn on the AC in a Jeep Cherokee?

Turning on the air conditioning in a Jeep Cherokee is a very simple operation, especially since Jeep has relocated the controls to a touch screen in the center console for many of the more recent model years of the vehicle. To begin, you will need to navigate to the screen and then to the home menu, where you may select “Climate,” which is placed at the bottom of the screen, as seen below. Once you’ve entered the temperature menu, you’ll see a number of symbols on the screen, which you can use to set the air conditioning to your liking.

Using the symbols in the centre of the screen, you can then choose which direction you want the air to come out of.

Jeep has made the decision to integrate temperature control settings into its infotainment system, which is a break from the traditional method of using buttons on the dash to manage the climate. Although the icons and buttons may seem a little different, they perform the same functions.

When the air conditioning in the automobile is functioning well, it is simple to enjoy the summer. Starting as soon as you get inside your automobile, the cold, pleasant air begins to chill you off immediately. It’s a wonderful sensation! However, when the air conditioner fails to provide cold air, emits bad scents, or has other issues, it may swiftly derail the day’s plans. Fortunately, you don’t have to let air conditioning problems get the better of you. Expert repair specialists have the knowledge and abilities to effectively fix your car’s faulty air conditioning system, whether it is a little problem or a severe problem.

Why is My AC Leaking?

There are a variety of factors that might cause an air conditioner to leak, but the most common is that rubber hoses and seals have lost their flexibility and are allowing liquids to pass through. In many cases, moisture is the root cause of this condition. Replacing the hoses and seals is a simple and effective solution to the problem.

How Do You Detect an AC Leak?

Our expertise is in leak detection! Despite the fact that we are not CSI investigators, we do have the abilities to discover a leak in your air conditioning system. We employ a variety of leak detection methods to track down the source of the problem. This includes the use of a black light to highlight the unique dyes contained in freon, as well as the use of a Sniffer instrument to detect the presence of freon. Both are meticulous and assist us in locating the leak so that we can repair it as soon as possible.

What’s That Smell?

Funky scents emanating from the air conditioning unit always raise suspicion, as they should. The presence of mold in the evaporator coil or a filthy cabin filter are both probable sources of AC scents, although they are virtually invariably the result of the former and the latter. When AC repair professionals are on the job, both of these issues are easily resolved.

Why Does My AC Get Warm After I Turn it On?

If the air conditioner blows chilly air when it is first turned on, but the air quickly heats up after that, it is probable that the unit is low on freon or that there is a freon leak. Of course, there are a few other possible reasons, such as a defective compressor clutch, blown fuses, blocked valves, or moisture build-up in the engine compartment.

Why is My AC Air Not Cool?

If your air conditioner is blowing warm or hot air, it is most likely due for a freon recharge. This is a straightforward job that our professionals can complete in a short period of time. The absence of cold air flowing from the air conditioning unit, even though the freon is completely charged and there is no leak, might be caused by vacuum leaks, failure of the blower motor, blocked expansion tubes, or other factors.

AC Blowing Hot Air: What’s Wrong? 6 Common Causes & Fixes For AC Warm Air

A freon recharge is most likely required if the air conditioning blows warm or hot air. Fortunately, this is a straightforward task that our professionals can complete in a short period of time.

The absence of cold air flowing from the air conditioning unit, even though the freon is completely charged and there is no leak, might be due to vacuum leaks, failure of the blower motor, blocked expansion tubes, or other factors.

  • The central air conditioner is blowing hot air
  • The mini-split air conditioner is blowing hot air
  • The car air conditioner is blowing hot air
  • And the window air conditioner is blowing hot air. Hot air is being blown by a portable air conditioner.

When the central air conditioner is blowing hot air, the mini-split air conditioner is blowing hot air, the car air conditioner is blowing hot air, and the window air conditioner is blowing hot air Hot air is being blown by the portable air conditioner.

How Air Conditioner Should Work (If Cooling Coils Aren’t Hot)

Your air conditioner only blows cold air when the cooling coils are cold. Period. When an air conditioner is in proper working order, the air is forced through cooling coils. The air is cooled as a result, and we enjoy a refreshing breeze from our air conditioner. Having heated cooling coils will not provide us with a cool breeze; instead, we will get a hot AC airflow output, which no one desires. To explain why the air conditioner is blowing hot air, we must first determine what is causing the cooling coils to get hot.

The following diagram depicts how a typical air conditioner operates.

  1. The refrigerant is compressed by the AC compressor, converting it from a gas to a liquid. This process is exothermic, meaning that it generates heat. All of that heat is directed outward
  2. The refrigerant in liquid form passes through the expansion valve and changes into gas
  3. This process is endothermic, which means that it pulls heat from the surrounding environment to operate. The cooling coils are in the’surrounding’ area
  4. This helps to cool the indoor coils down. Air is forced through these frigid cooling coils, and we are treated to a refreshing breeze from our air conditioning unit.

If your air conditioner is blowing hot air, it means that something is wrong with the operation. Either the compressor is not compressing adequately (completely), the expansion valve has failed, or there is a general deficiency of refrigerant in the system overall. Examine the following to determine what is wrong with your hot air blowing AC:

6 Common Causes Of Air Conditioner Blowing Hot Air

There are a variety of reasons why your home’s air conditioner is spewing warm air. The majority of the time, overheated cooling coils are caused by a problem with the refrigerant cycle (low freon, compressor issue, valve issue). On a less frequent basis, the reason may be of an electrical type (thermostat issues, power issued). We’ll go through each of the issues that might be causing your air conditioner to blast hot air one by one. Here is a comprehensive list of the most common reasons why your air conditioner is spewing warm air:

  1. Low refrigerant concentrations (most common cause). Without freon, heat exchange is difficult
  2. You may have a leak in the refrigerant lines
  3. Loss of compression by the air conditioning compressor
  4. And other problems. A clogged air filter (resulting in decreased airflow)
  5. A clogged expansion valve (resulting in inadequate refrigerant expansion)
  6. A power problem, such as a blown fuse or a tripped circuit breaker Problem with the thermostat: incorrect setting or improper wiring

Let’s start with the most common reason for your air conditioner to produce hot air:

1 Low Refrigerant Levels Are The Cause Of AC Blowing Warm Air

When the refrigerant levels in the air conditioner are sufficient, the air conditioner is effective in exchanging heat (converting hot air into cool air). The fundamental premise of how air conditioning works is the compression and subsequent expansion of refrigerant. Low freon levels are the most typical reason of an air conditioner that blows warm air. As a result of the scarcity of freon, the freon expansion (which converts it from a liquid to a gas) is not adequate. This indicates that the cooling coil will not be effectively cooled; in fact, it may begin to get warmer the longer we leave the air conditioner running on high.

For freon levels to be dangerously low, there is only one possible cause: a leak in your refrigerant lines.

Leaks in refrigerant lines are not unheard of in the HVAC industry.

Even if you have a few technical abilities, you can attempt to do the task yourself (although this is not recommended).

You may learn more about how to change the freon in a window air conditioner by visiting this page (window AC serves as a good example). Following the restoration of the freon levels, you should notice that your air conditioner is running correctly (blowing cold air again).

2 Faulty Compressor Leading To AC Blowing Hot Air

If your freon levels are OK, it’s possible that a defective AC compressor is the source of your AC’s hot air blowing. The only duty of an air conditioner compressor is to compress the freon. Freon that has been thoroughly compressed will undergo complete expansion and will completely cool down the cooling coils. If the air conditioning compressor does not perform properly and the freon is not entirely compressed, the freon expansions will be insufficient as well. It is possible that cooling coils will not be effectively cooled as a result of this.

  • This results in – you guessed it – the air conditioner spewing heated air.
  • Compressors have a reputation for being difficult to repair.
  • This is also what the majority of HVAC technicians will perform.
  • When dealing with larger units (central air, mini-splits, and heat pumps), it is preferable to have a professional do the work.
  • When the air conditioning compressor is replaced or repaired, the freon compressor will return to normal operation.

3 Clogged Filters (Not Dirty) Can Cause AC To Start Blowing Warm Air

The air conditioner must maintain a suitable amount of airflow in order to perform correctly. If you fail to do so, you may experience hot air flowing from the air conditioner. Clogged air filters are one of the things that might drastically impede airflow if they are not cleaned regularly. If the air filters become clogged, the airflow will be dramatically decreased, and every component of the air conditioning system will attempt to adjust for the lower airflow (because its goal is to achieve a low temperature, as set by the thermostat).

Located on the capillary tube that connects the outside unit/part to the inside unit/park, the expandable valve allows for greater flow of air.

The airflow must be significantly limited in order for the air conditioner to begin blowing warm air (at a temperature greater than the inside temperature).

Air filters that are clogged and merely require cleaning are not the source of the warm air coming from your air conditioning machine.

AC filters that are clogged are a problem. In this scenario, the solution is straightforward: simply change the air filters. When the airflow returns to normal, the air conditioner will resume regular operation.

4 Clogged Expansion Valve Causes Hot Air Coming From AC

The expansion valve’s primary function is to efficiently discharge refrigerant liquid through the system and expand it into gas form. When this expansion occurs, it causes ‘chills’ to be transmitted throughout the cooling coils. That is precisely what causes the cooling coils to cool down. Due to faulty operation of the expansion valve, the amount of refrigerant that can be expanded into gas will be insufficient, and the cooling coils will not be appropriately cooled. While the air conditioner is functioning, it is possible that warm air may be blown out of it.


To solve the problem, you must first unclog the pipes, which is a much simpler task said than done.

After the clog has been removed, the refrigerant cycle should be restored to normal, and the air conditioner should no longer blast warm air.

5 Power Issues: Blown Fuses And Tripped Amp Breakers

In addition to problems with the refrigerant cycle, electrical problems can also cause your air conditioner to spew heated air. The first step is rather straightforward; simply inspect all of the outlets and wires. Generally speaking, this is OK. One item we can overlook – and which could result in excessive heat emanating from your air conditioner – is blown fuses and tripped circuit breakers. To safeguard our air conditioner from electrical surges, we employ both fuses and amp breakers. If there is something wrong with them — a blown fuse or a tripped amp breaker, for example – you may be experiencing some strange consequences.

Check to see whether your air conditioner’s fuse has blown or if the amp breaker has been tripped.

6 Thermostat Issues: Wrong Setting Or Wiring Problem

It may seem obvious, but if your thermostat is set at a setting higher than the room temperature, your air conditioner will blast heated air. This is generally the first item we double- and triple-check before moving on. In the vast majority of circumstances, the thermostat setting is satisfactory. The new thermostats are causing the biggest problems. If your new air conditioner is spewing hot air, there is a possibility that the thermostat is not correctly connected. The incorrectly wired thermostat is a complete jumble; a muddle that may result in some unexpected occurrences, such as hot air entering from your air conditioning machine.

If your air conditioner was operating normally previously, it should continue to operate normally today.

For example, the possibility of a wire falling out of the thermostat socket is quite remote. This thermostat wiring guide may be used to determine whether or not your thermostat is correctly connected (blue wire or B is usually responsible for air conditioning).

Final Note

It may seem obvious, but if your thermostat is set at a degree higher than the room temperature, your air conditioner will blast warm air instead of cooling air. This is generally the first item we double- and triple-check before moving on to anything else. The thermostat setting is usually satisfactory. It is the new thermostats that are causing the greatest concern right now. If your new air conditioner is spewing hot air, there is a potential that the thermostat is not correctly connected in the first place.

This is only relevant to air conditioners that are either brand new or have just been connected.

Taking the example of a thermostat socket, the risk that a wire may come loose is negligible.

Four Common Reasons Your Jeep Wrangler Heater Is Not Working

ByMatt Konkle, Editor-in-Chief of Torque Magazine Every day, CNN, NBC, your local television or radio station, and most likely even your social media feed, broadcast weather forecasts about the bone-chilling cold. Even those of you living in extreme southern Florida and, for example, the San Diego region of California, might expect to see a cold front or two during this time of year. Moreover, for some of you, this may be the first time in a long time that you’ve turned on the Jeep heater, only to discover that nothing comes out when you turn the dial back.

Hopefully not, but hey, it does happen from time to time.

Let’s start with a brief explanation of how the Jeep heater operates because hot air must originate from someplace, right?

The thermostat in your Jeep opens when the vehicle achieves its ideal temperature, allowing coolant from the cooling system to run through the engine, removing heat and delivering it to the radiator, which then sends it to the heater core, which then distributes it through the Jeep If the heater in your Jeep Wrangler has ceased working, it is likely that one or more steps in this procedure have failed.

The following step is to apply Occam’s Razor.

It is possible that your Jeep’s heater is not functioning correctly for a variety of reasons.

Take note, however, that the more recent the vehicle (such as JL Wranglers and JT Gladiators), the more electronics are likely to be involved in the heat-generating system.

As a result, owners of newer Jeeps may find it useful to take their vehicles to the dealership or a trustworthy technician for a diagnostic.

Heater Blower Motor / Resistor

This is the individual who is in charge of blowing air through the hot heater core, via the Jeep’s ventilation system, and into the vehicle’s interior. The fan is normally positioned under the glove box, and if it fails, you may still be able to obtain cold or warm air via the vents, but the pressure will be significantly reduced, regardless of the fan speed you choose. You may also hear a grinding or rattling sounds coming from the fan region, which indicates a problem with the fan blades or bearings.

It is also unlikely to have an impact on the vehicle’s other components.

If the blower motor appears to be in good working order and there is no sign of a pressure problem, but the fan only operates at certain speeds, this might suggest a problem with the resistor.

If the resistor fails completely, there will be no airflow through the Jeep’s vents at all.

Coolant Level

Your engine will run hotter if you do not have enough engine coolant (antifreeze). Ironically, it will also prohibit your car from producing enough heat to keep you warm. Due to low coolant levels, there will be insufficient (or no) coolant in the heater core, and as a result, there will be nothing hot enough for the blower motor to push into the cabin. Fortunately, it is a short and simple procedure. If the antifreeze level in your engine’s coolant overflow container is low or completely depleted, you can top it out with the appropriate amount of antifreeze.

  1. That can be a bit hard for people with later model Wranglers.
  2. You may now purchase coolant that is intended to operate with all varieties, which is useful when you want to top off or add to your existing coolant supply.
  3. It is important not to make the error of putting concentrated coolant in your overflow container!
  4. It is also important to note that adding coolant to the overflow bottle or removing the radiator cap should never be attempted when the engine is hot and/or under pressure, and this cannot be underlined enough.

You run the danger of burning yourself. Always wait until the engine is completely cold before starting it.


The thermostat in your Jeep is a valve that helps to regulate the temperature of the engine. This implies that while the engine is cold, the valve remains closed, preventing coolant passage to the engine and allowing it to warm up more quickly. Once the engine reaches a specific temperature, the valve opens, allowing coolant to flow into the radiator, where it can help to cool the engine and prevent the Jeep from overheating and breaking down. In any case, failure of the valve occurs when it begins to fail in either the closed or open state.

When the valve is open for an extended period of time, the engine runs colder than normal, which should result in the check engine light turning on.

While this does not pose an immediate threat to your engine, it should be addressed as soon as possible in order to restore complete performance to your engine as well as the Jeep’s heating system to the vehicle.

Also, as little driving as possible until the replacement is available.

Heater Core / Hoses

The heater hoses in your vehicle are the vessels that transport coolant from the engine to the heater core. They are often sold as a pair, including an inlet and an outlet. It is possible for coolant to leak out of a faulty hose due to a connection problem, rust, or a tear in the hose in some way. You should be able to smell coolant in the engine compartment when this occurs. That coolant may have splashed over the heater core, which means the odor is likely to have migrated into the cabin from outside it.

If there is no coolant smell, but there is a problem with the heater, it is still a good idea to check these hoses for heat, just to be safe.

If this is the case, the coolant is not flowing correctly, and you may have air trapped in the pipes or a blocked heater core that requires flushing out.

AC Blowing Warm Air: What’s Wrong?

The following are some of the most prevalent reasons why air conditioners blow warm air:

  • A dirty air filter
  • A frozen evaporator coil
  • And other issues Errors with the thermostat settings
  • Failure of the outside unit to get electricity
  • Refrigerant leak

Dirty Air Filters

When the cooling system’s filter becomes clogged, the air conditioner is unable to effectively circulate air throughout the system. It is important to check your air filter to verify that it is clean if your air conditioner isn’t properly cooling your house. If your air conditioner isn’t effectively cooling your home, it is important to figure out what is causing it to blast warm air. Check to see whether the present air filter is unclean and replace it with a new, clean filter to see if the problem with the heated air is resolved.

Frozen Evaporator Coils

The evaporator coils of your air conditioner collect heat from the air in your home in order to begin the cooling process. Condensation is produced as a bi-product of this process, which is why air conditioners are equipped with a drip pan and condensate drain to collect the extracted moisture and remove it from the system. When moisture accumulates on the evaporator coils, they have the potential to freeze. As a result of the frozen coils, heat cannot be transferred, and you will notice warm air flowing from your air conditioning system when this is the case.

  • If you notice frost or ice on the coils, the best course of action is to wait for the coils to thaw, which may take up to 24 hours depending on the severity of the freeze.
  • A heat gunor hair dryer can also be used to defrost frozen coils that have accumulated ice over the course of time.
  • Check to see that the system’s drop pan and condensate drain are not blocked, since this will prevent the system from adequately removing the moisture.
  • Poor airflow, refrigerant leakage, system failure, and other factors can all result in frozen evaporator coils in a refrigerator.

Thermostat Settings Errors

A minor error at the thermostat might sometimes result in an air conditioner that does not provide enough chilly air. In contrast to AUTO, if the blower fan is set to ON rather than AUTO, it will operate all of the time rather than just during a cooling cycle. In between cooling cycles, the air coming out of the vents may feel warm to the touch. If you have an air conditioner that is blowing hot air, check the settings on your thermostat. Make certain that the fan is set to AUTO and that the COOL setting is chosen.

Lack of Electricity

In a split air conditioning system, both the interior and outdoor components must be operational in order for cooling cycles to be completed and coolness to be delivered to the residence. If the power supply to your home’s outside unit is stopped, the interior components are the only ones that are operational, resulting in warm air being forced through the home’s ventilation system.

Check to ensure that your outside unit is powered. Check the electrical panel in the home to make sure the breaker has not been tripped; if necessary, reset the breaker. Also, make sure the ON/OFF switch on or near the outside air conditioning unit is set to the ON position.

Refrigerant Leaks

Leaking refrigerant might also be a contributing factor to your air conditioner producing hot air. A leak in the system causes the refrigerant to escape and leave the air conditioner with insufficient charge to finish its cooling cycles successfully. As a result, the air you breathe inside is warmer than it should be. Unfortunately, refrigerant leaks can only be repaired by a professional HVAC technician who has received the necessary training and qualifications in refrigerant handling. Other indicators of a refrigerant leak include the following:

  • Evaporator coils that have frozen
  • Hissing noises coming from the air conditioner’s components
  • Electric costs that are increasing without any explanation

How to Know If Your AC Compressor Is Bad

When it comes to air conditioning systems, the compressor is one of the most significant components. The compressor’s primary function is to keep the refrigerant running and to maintain system pressure. When the unit is running, it cycles on and off continually in order to cool the house. Because of the constant on and off cycle, it can accumulate a substantial amount of wear and tear over time. Know the symptoms that your air conditioning compressor may be failing so that you can stay on top of any potential repairs or replacements that may be required.

  • When a compressor’s performance begins to deteriorate, the component will struggle to switch on.
  • Distinct problems with the compressor might result in a variety of different sounds.
  • In the event that a bearing is leaking, you may hear an audible screeching noise.
  • A change in the flow of air or the temperature Whenever a compressor begins to fail, the airflow output of the vents will begin to drop.
  • If you observe that the amount of chilly air coming out of your vents is reducing, contact an air conditioning repair provider.
  • Instead of producing cold air, a faulty compressor is unable to regulate the refrigerant flow, resulting in the production of warm air.
  • Moisture that is leaking It is never a good thing when there are leaks around an air conditioning unit.
  • A faulty compressor, on the other hand, might cause refrigerant to leak.
  • It can cause a variety of health problems, including headaches, nausea, inflamed eyes, coughing, and others.
  • If the leakage is not addressed, the compressor may run out of refrigerant, get dry, and eventually cease to function completely.
  • If there is any indication of prospective wear and tear, it should be investigated as soon as feasible.

When in doubt, contact an air conditioning repair specialist to come out and evaluate your system. Having the assurance that your family will be kept cool on a hot summer day is well worth the investment.

Air conditioner randomly blows warm air

After a bit of troubleshooting, I was able to resolve the issue. I just let the Jeep sit idle for about 20 minutes with the air conditioning on full blast. At first, I couldn’t figure out how to reproduce my situation. The air conditioning wouldn’t turn on at all, however there was good drainage of the humidity. Then I started tossing switches in different directions. We played with the blower settings and turned the air conditioner on and off several times. It wasn’t long until the compressor stopped running and the air became too hot to breathe.

Then I used a jumper wire to complete the circuit by connecting it to the connection.

After that, I disconnected the connection from the low pressure switch.

The engine’s rpm slowed down a little.

As a result, it appears that both the high and low pressure switches are functioning properly, as you can hear an audible change in the engine rpm that you normally hear when the a/c is turned on, and when either switch is disconnected, the revs return to where they should be when the a/c is turned off.

I swapped out the relay labeled ABS with the relay labeled a/c clutch after moving the relay labeled ABS.

I’ve done a little research and it appears that many individuals who are experiencing the same problems as mine are removing shims from the a/c clutch and reporting positive outcomes.
