AC doesn’t work – Dodge Neon?

The most common reasons a Dodge Neon ac isn’t working are a refrigerant leak, an electrical climate control issue, or a problem with the air conditioning compressor.

  • What are common reasons my Dodge Neon has air conditioning problems? While there are a variety of reasons your Dodge Neon air conditioning won’t work, the most common 3 are a refrigerant leak, an electrical climate control issue, or a problem with the air conditioning compressor.

What causes car AC to suddenly stop working?

There are several things that can cause electrical problems for your car’s air conditioning. These can include failed switches, a blown fuse, a problem with the control module or something else. Fuses can short out and make the A/C stop working or a loose connection can create an electrical short that is easily fixed.

Why is my AC running but not cooling in my car?

The most common causes of broken air conditioning are leaks or compressor issues. If your air is blowing cool but not cold, the problem could be a clogged filter, cooling fan problem, radiator trouble, or it could simply be that you need to recharge your AC.

Why has my AC stopped working?

If your air conditioner is not working, it can be caused by a variety of reasons. Common reasons include dirty or blocked air filters. In other cases, there can be issues with your compressor or refrigerant. This can lead to your ac not blowing air, not turning on, or it just doesn’t seem to be working properly.

Can a blown fuse cause AC not to work?

First of all, your electrical system might be having problems. While this prevents serious trouble such as electrical fires, it also means that a single blown fuse can cause the entire air conditioner to stop working.

Why is the ac not blowing air?

The most common problems that cause a lack of airflow include frozen coils, broken fan and restricted airflow due to dirty air filters or vent obstruction. However, there are many other issues that can lead to minimal airflow, so it may be necessary to ask the professionals.

How do I know if my AC fuse is blown?

Test the load: If you saw a voltage reading during the previous step, run the same test on the “load” side of the fuses. You should again see a reading between 220 and 240. If you see a voltage reading on the “line” side but not the “load” side, it means you have a blown fuse.

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.

Why is my AC blowing warm air in my car?

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 air conditioner not as cold?

If your air conditioner will turn on, and your thermostat is set properly, but your system is not cooling you may have a dirty or blocked air condenser. If your air conditioner is still not cooling air, you may have a problem with your compressor or refrigerant and will need to contact a professional.

How do I fix my air conditioner that wont turn on?

If your window air conditioner won’t turn on, it may be that the fuse has blown. First verify that you are getting power to the unit and then unplug the unit and remove the cover. Locate the circuit board and check for a removable fuse. If one is found, look for signs that it has blown or use a multi-meter to check it.

What do you do when your AC won’t turn on?

AC Not Turning On? Try These Tips:

  1. Check the shut-off switch.
  2. Ensure the thermostat is set to COOL.
  3. Check the power switch on the inside unit.
  4. Check for a tripped circuit breaker or blown fuse.
  5. Main electrical panel.
  6. Shut-off box near AC unit.
  7. Try a System Reset.
  8. Check the condensate drain line.

Where is the air conditioner fuse located?

The fuse is a wire inside a glass casing, found in the disconnection box connected to your AC. The fuse is a protective measure meant to protect your air conditioner from electrical damage.

Can a dirty air filter cause AC not to cool?

As a result of the buildup, a dirty filter will also cause poor cold airflow in your air conditioning system. That cold air will be trapped inside your air conditioner, causing ice to form on its coils. Once that happens, your air conditioner will freeze up and become inoperable.

AC Not Blowing Cold Air: I Am Having a Problem with the Air .

There is an easy technique to check the condition of your compressor. The low pressure was interrupted. If you look on your firewall, you will see a black connector plugged into an aluminum box on the fire wall where the smaller metal tube of your air conditioner connects to it. Remove the connection from the plug and insert a jumper wire into the connector. Your compressor will start up and run for a while. If this is the case, don’t be alarmed; simply look at your compressor; there is another 2 prong socket (the smaller plug on top where the lines are placed) that serves as your high pressure switch off.

If the compressor starts up when the high pressure jumper is engaged, it is likely that the ground wire from the high pressure cutoff to the fuse box is faulty.

If you peek under the hood, you’ll notice a piece of flex loom that is connected to the fuse box.

It will be the brown/orange wire that will be used.

  1. TAH DAH, you’ve successfully repaired your faulty wire.
  2. If it doesn’t work, please let me know.
  3. And, based on the sounds of things, I believe you are just short on freon.
  4. Neons, on the other hand, are an exception.
  5. Although I assume there is a normal amount of leakage from the connections on the compressor, I believe this is the result of bad design.
  6. Furthermore, because the High and Low side fittings are different diameters, it will only connect in one direction, making it impossible to make a mistake.

Dodge Neon: AC Compressor Not Turning On – Diagnosis

Regardless of where you reside, if the air conditioning compressor in your Dodge Neon is not working, it may turn a nice journey into a nightmare (particularly if you have kids that are riding with you). AC compressor pulley is always driven by either the serpentine belt or a dedicated belt (which will vary on the model year and engine type), therefore it is constantly running. It makes use of a clutch to grip the pulley and circulate coolant through the air conditioning system of your Neon. If this clutch does not engage, the air conditioning compressor will not operate.

It’s best to do it in a peaceful place.

Something else is the source of the problem.

This article will help you if your Dodge Neon’s air conditioning isn’t blowing cold at all. To figure out why your Dodge Neon’s air conditioning isn’t working, follow these instructions.

1. Inspect Your Neon’s AC/Serpentine Belt

As previously indicated, the alternator compressor in your Neon may be driven by the same serpentine belt that drives the rest of the engine’s components. Alternatively, it may be spun by a separate belt. If there are two belts, they will both be linked to the crank pulley at the same point. Check the belt to check whether it has any cracks or if it is polished. It’s possible that the belt is no longer capable of turning the compressor. If it is an independent belt, it is possible that it will be completely absent without you noticing.

The clutch is not receiving a signal to engage when it should.

In either case, the AC compressor is receiving a directive to switch on but is no longer able to do so, indicating that it should be replaced.

2. Turn the Compressor by Hand

When your Neon’s air conditioning compressor is not in use, it should be able to be turned by hand. It goes without saying that you’d want to do this with the car turned off. Electric fans are frequently used to find it. Even if the key is not in the ignition, treat them as though they can be turned on. You do not want to spin the pulley where it is joined to the belt since this might cause damage. The front of the compressor has a 1/8-inch space between the belt and the piston. This gap is necessary for the operation of the compressor.

If it is not freely moving, this is a very good sign that the compressor has been jammed and must be replaced immediately.

3. Check Your Neon’s AC Wiring Harness

Because the clutch compressor is only a few feet away from the road, it is possible that wire damage will accumulate over time. Check the harness to ensure that it is free of any openings or shorts before using it. Whether everything appears to be in working order, it’s time to move on to checking the relay and seeing if you can manually switch on the compressor. While you’re at it, check the fuse for the electricity flowing to the AC compressor relay, which is also located near the compressor itself.

4. Test the Compressor Clutch

You may use a jump wire to check whether or not the AC compressor clutch on your Dodge Neon is functioning correctly. It is necessary to find and turn on the compressor relay first, though. The compressor clutch turns the compressor by grabbing the pulley with an electromagnet and turning it. As soon as this magnet is triggered, you should hear a ‘clunk’ sound (particularly with the engine off). A jump wire will be required. The video included just below does an excellent job of explaining the entire procedure in detail.

Now that you have manually instructed the AC compressor to switch on, it should begin to operate as expected. If it does not, this indicates that the compressor is not reacting and that it will have to be replaced.

r/Cartalk – 2004 Dodge Neon AC compressor won’t turn on. Relay Good, AC just recharged. Bypassing relay turns it on.

Dodge Neon from 2004. Transmission that is automatic. 2.0 liters of four-cylinder power I’m not an expert in automobiles, so I may misinterpret a few phrases, but I’ll do my best to explain them as well as I can. The air conditioner has ceased pumping chilly air. In the past, something like this has happened. Before, every time I brought it in, they claimed to have recharged it, and then it started working again. (I’ve done this approximately three times in the past, the most recent time being about two years ago.) So, like I’ve done in the past, I brought the car in today and they hooked it up to the machine to evacuate and recharge the air conditioning.

  • (Please note that I have relocated and that this is a different mechanic.) It appears that the AC clutch (or the air compressor, or both?) is malfunctioning.
  • I was made aware of the relay.
  • The compressor sprang into gear.
  • Is it possible that the relay is malfunctioning?
  • Changing it out for the horn relay has no effect on anything.
  • So, what’s the next step for me?
  • The relay appears to be in good working order, however the compressor is not turning on.
  • Finally, a final thought.
  • It’s possible that anything went wrong since the last time it was recharged and functional.
  • Thank you for any assistance.

A/C Compressor suddenly wont engage

My girlfriend has a ’98 Plymouth Neon SOHC automatic transmission. Earlier afternoon, the air conditioning on it quit working for no apparent reason. It went from blowing chilly to completely not functioning all of a sudden. We recently had the evaporator fixed, the system inspected for leakage, had the system recharged with 134, and everything has been running well since. That happened less than a month ago. Nothing indicated that it was running short on refrigerant, such as reduced cooling, quick cycling on and off of the compressor, or anything else.

  1. I inspected the vehicle and searched for the obvious—the a/c belt, fuses, and everything else I could think of.
  2. I did notice that under the hood, in the power distribution center, there is a giant relay-looking device (I’m really not sure what you call it) labeled air conditioning, so I’m wondering that maybe it went bad and that’s what’s causing the problem.
  3. Do you have an estimate of how much it will cost?
  4. I’m hoping it’s not the compressor because this car has been a money hole since it was purchased with only 80K miles on it-first the head gasket failed, then the spark plug tubes began to leak, then the evaporator, and now this.

I’m very aware that I’m forgetting certain things as well. All of this **** has also been quite expensive to repair. Please assist me in getting rid of this piece of junk before I sell it and buy a Honda or anything. Please accept my apologies for ranting here.

air conditioning problems, wouldnt take full charge no A/C

PostbyEbd on Wednesday, June 16, 2010 at 9:21 a.m. Purchase a vacuum pump. Recover all of the freon that is currently in the vehicle. Connect the vacuum pump to one of the lines and let it run for around 20 minutes. This will draw out all of the moisture and/or oil that has accumulated in the system. You may now begin charging the system. Connect it to the low side of the frame. (You perform all of your service tasks from the lower level.) Start your automobile and crank up the A/C to maximum capacity.

  1. The compressor is shutting down at this point.
  2. Then add some freon to the mix.
  3. After you’ve given your initial injection and waited, you can refill the system if it’s necessary.
  4. If it doesn’t, the air conditioning clutch will disengage, and your air conditioning will stop working.

AC blows cold then warm Dodge Ram

Dodge Ram 1500 with intermittent air conditioning The compressor shuts down, blows cold, then warm, warm air conditioning. The air conditioning system is divided into three sections: the sensors (high and low pressure sensors, as well as the AC on/off switch), the command unit (the powertrain control module-PCM), and the ‘doing’ components (the compressor and the fan) (the compressor clutch relay, compressor clutch, and the compressor). Check the compressor clutch coil to verify if it is in excellent working order.

  • The low pressure sensor, on the other hand, gives the information necessary to determine when to cycle the compressor on and off.
  • Finally, there’s the compressor clutch and the compressor itself (if applicable).
  • When the clutch stops cycling, the first thing I’d want to know is if it’s getting power from the compressor clutch relay.
  • You may check for battery voltage on the dark blue/black wire by disconnecting the electrical connector from the clutch, starting the engine, turning the A/C to the maximum setting, and then removing the electrical connector.
  • An insulated black/white wire connects the compressor clutch ground to a splice on the transmission’s top, which is located between the clutch connector and the transmission.
  • A faulty clutch is most likely to blame if you’re getting power and ground at the clutch connector but the clutch isn’t engaging when you try to engage it.
  • Whether you’re not getting power at the clutch connections, I’d check to see if the compressor relay is receiving a ground connection from the PCM.

Fuse J (10A) at the power distribution center provides electricity to the compressor clutch relay contacts, which in turn supply power to the compressor clutch (PDC).

To begin, remove the compressor clutch relay, start the engine, and set the A/C to the maximum setting.

To determine whether or not you are receiving voltage, check for PCM ground on terminal 85 of the same socket.

Consider replacing the relay with another one with the same component number if you’re seeing voltage and ground on the other end.

If you are still not getting power at the clutch, it is possible that you have a corrosion issue inside the PDC or that there is an open in the dark blue/black wire that connects to the clutch assembly.

Here’s how the sensors are supposed to function.

In addition, when you turn on the A/C and hold it there for a long period of time, the switch completes the path to ground on the black and orange wire that terminates in the middle of the dashboard.

Following that, it examines the high and low pressure switches.

Whenever the refrigerant pressure is higher than the low limit, electricity is routed via that switch and out to the high pressure switch (which is situated on the rear of the A/C compressor) via a dark blue cable.

If the refrigerant pressure is greater than the high pressure limit, power flows out of the high pressure switch on a light green/white wire.

When the PCM is turned on, it’s seeking for continuity via the sensor switches and finally to ground.

That is its cue to deliver ground to the compressor clutch relay on the A/C compressor.

When the connections in both the low and high pressure switches are closed, the PCM delivers ground to the A/C compressor clutch relay, which is controlled by the PCM.

For example: intermittent compressor clutch coil, poor compressor clutch relay, corrosion in the PDC, an open in the wire to the compressor clutch, intermittent ground on the sensor side are all possible culprits for intermittent compressor clutch coil.

What is an AC Evaporator Core?

Let’s start with the fundamentals, shall we? For example, the absolute fundamentals. AC is an abbreviation for air conditioning. Hopefully, you were previously aware of this. With that out of the way, let’s move on to the evaporator core, which constitutes a significant portion of your air conditioning system’s overall performance. What is the significance of the evaporator core in an air conditioning system? As the name implies, it is the component of the air conditioning system that is responsible for, you know, chilling the air.

  1. That appears to be something of significance, don’t you think?
  2. I won’t bore you with all of the details because, frankly, I don’t believe you are very interested in any of them anyhow.
  3. An expansion valve or an orifice tube is responsible for delivering liquid refrigerant to the evaporator core.
  4. The blower motor is also working at the same time, forcing heated air across the evaporator.

You may avoid leaving sweat stains all over your expensive automobile seats by doing so. Evaporators are exceptionally long-lasting, and you will almost never have to replace yours in your lifetime. But, well, you simply never know what may go wrong in this world.

Symptoms of a failing AC Evaporator Core

If the evaporator in your air conditioning system fails, your air conditioning system will be unable to produce cold air effectively. It’s impossible to bring cold air into your cabin unless it’s a really chilly day, in which case your fans will come on automatically. The temperature of the air is determined by the condition of the air conditioning evaporator. If it’s just getting started, you could still experience some chilly air; however, it will be more in the range of a brisk spring day’s worth of cold rather than the depths of winter cold.

How urgent is an AC Evaporator Core replacement?

That actually depends on the situation. How crucial do you consider air conditioning to be? A faulty evaporator in your air conditioning system will not make your vehicle any less safe to drive. On a hot day, it’s just going to make things more uncomfortable. It’s all up to you.

99 Neon backup light fuse blows/AC quits working.

Dh27110, 25th of November, 2009, 8:11 p.m. Strange situation here: the backup light fuse on a 1999 Neon blows, and the air conditioning stops blowing cold. I replaced the fuse and now the air conditioning is blowing chilly. Do you have any suggestions? I discovered that this is the 8th fuse, which is rated at 10 amps, and that it controls the rear window heat, fan relay, air conditioning cycle switch, and backup lights. Is there anyone else that is experiencing the same issue?: banghead:jason-1995fbody 25th of October, 2009, 09:27 p.m.

  • I’m going to spend some time with it over the next couple of days to get a better feel for how it works.
  • That is a significant number of objects being powered by a single 10 amp fuse.
  • What a pathetic little fuse!
  • Obviously, the quickest and most straightforward method of diagnosing the problem is to attempt each of the steps listed above one at a time until the fuse blows.
  • You said that the fan relay was being considered.
  • Clean up the ground wires to guarantee a healthy ground since a faulty ground can create a variety of difficulties, including fuses that are not working properly or malfunctioning.
  • 2009-06-26 06:58: dh27110-26-2009 AMI is perplexed as to why they combined the a/c switch, rear window heat, fan relay, and ‘backup’ lights into a single fuse panel.

The first time I posted this topic, I hadn’t looked at the owner’s handbook; instead, I glanced at the fuse access panel, which showed only the backup lights, which was what puzzled me about the a/c not functioning; however, once I looked at the manual, I discovered the rest of the information.

My idea would be to ‘leave the keys in the ignition, the windows down, and park on the street at night,’ but I’m not the one who’s driving it.: On October 26, 2009, at 11:31 a.m., mopar rocks posted a jerking message.

Oklahoma is too far away for me to be able to ‘help’ you out on this.

I’m sure it’ll work wonders for troublesome automobiles!

The time is 9:40 a.m.

First and foremost, you can securely utilize a fuse socket with a current of up to 20 amps.

However, I am experiencing the same problem.

It is necessary to detach the harness and clean the connections before reassembling it.

This has been done twice on my 2001 Neon (which has over 135,600 miles on car!) and it will be done again at the next oil change. Until then, I keep a large supply of 15 amp fuses in my glovebox. Automotive Network, Inc., Copyright 2022. shrug
