Caravan blows cold air? (The answer is found)

  • A bad sail switch is an extremely common issue with RV heaters blowing cold air. The sail switch is a small switch that opens once your heater fan gets up to full speed which then allows the heat to come out. If the switch is blocked by dust, hair, debris, rust, insects, or anything else, it will not open and your RV heater will blow cold air.

Why is my Dodge Grand Caravan blowing cold air?

The most common causes that hinders normal operation of air conditioning system on your Dodge Grand Caravan are dirty cabin air filter, refrigerant leak, dirty or clogged condenser, dirty or clogged evaporator, bad blower motor, defective compressor, faulty blend door actuator or any fault in the electrical system.

Simple Steps to Reset Dodge Caravan Air Conditioner

The Dodge Caravan is one of the most attractive cars that the Chrysler Group has introduced recently. Since taking over the market in 1984, the Dodge subsidiary of this corporation has performed admirably in terms of fulfilling client expectations and beyond them. The car is equipped with a strong engine, comfortable seats, and up-to-date technological amenities. In addition, the van is equipped with a high-quality air conditioner, which allows you to travel comfortably even in hot and humid weather conditions.

Three Steps to Reset Dodge Caravan Air Conditioner

  1. When your Dodge Caravan’s air conditioning isn’t working properly, the first thing you should do is start the vehicle. Once you’ve inserted your car key, make sure to turn it to the ‘On’ position to start the vehicle. ‘Panel’ should be selected from the mode selection menu
  2. This will send the air just to the top portion of your body. This is a straightforward procedure that you may complete on your own. However, if you want expert assistance, you may contact the local Kelly dealer in Allentown, Easton, or Philadelphia
  3. Three buttons are located on the left side of the Dodge Caravan’s air conditioning controls. Press and hold the topmost and bottommost buttons for a few seconds. While the top AC button controls the rear wiper, the lower AC button controls the amount of washer fluid used by the rear wiper. Check the air conditioning light
  4. It should be illuminated and flashing. If you see the flash, you’ve almost completed your task. Customers in Allentown, Easton, and Philadelphia may contact a reputable dealership to get their Caravan AC reset quickly. After you see the flash, release both of the buttons on the steering wheel. The system will begin to be reset at this point. During the resetting process, air is blown out of the vents at random intervals, causing the room to become uncomfortable. As soon as the operation is completed, the top AC button will begin to flash rapidly. To complete the Dodge Caravan air conditioning reset, press the top conditioning button. Follow the instructions outlined above to reset the Dodge Caravan’s air conditioning and make your travel more enjoyable. Kelly Jeep in Emmaus, Pennsylvania, provides expert and efficient Dodge Caravan air conditioner reset services to customers in the Allentown, Easton, and Philadelphia areas.

Why Does My Car Air Conditioner Blow Cold Then Warm?

On a hot summer day, there’s nothing quite like turning up the air conditioning in your automobile to keep cool. There are few things that feel better than a refreshing burst of air! But what if your car’s air conditioner alternates between blowing cold and warm air? If you get the impression that your air conditioner is playing tricks on you and isn’t blowing cold air for an extended period of time, it may be time to bring your A/C troubles to your nearest Firestone Complete Auto Care. There are a variety of factors that might be causing your car’s air conditioning to blast cold air first and then warm air second, including:

A Leak in the A/C System

The most typical reason for a car’s air conditioning to progressively lose its cool is a little refrigerant leak. Moisture and refrigerant combine to form a corrosive acid that eats away at the seals, valves, and rubber hoses in the air conditioning system. This is the most common source of leaks in air conditioning systems. Because there isn’t enough refrigerant in the system to cool things down, a leak in your A/C system might be causing the unit to blow warm air instead of chilly air. Worse still, the acid can corrode the interior of your compressor, causing metal shards to spread throughout your A/C system and resulting in extensive damage, obstruction, and component failure.

A Faulty Compressor Clutch

The air conditioning compressor clutch is one of the most critical components of your vehicle’s air conditioning system. It enables the pulley to engage and disengage from engine power as needed, ensuring that the compressor only operates when necessary. Because it is constantly cycling on and off, it is subjected to wear and tear with each usage of your air conditioning system. When there is a problem with the compressor clutch, your air conditioner will not be able to keep up with the demand for cool air.

A Failing Expansion Valve

If your air conditioner alternates between being hot and being chilly, it is possible that your expansion valve is failing. During the evaporation process, the expansion valve relieves pressure from liquid refrigerant, which allows it to expand from a liquid to a vapor state. It is possible that the refrigerant flow will be restricted or too unconstrained if the valve is obstructed. A little obstruction in refrigerant flow might cause a mechanical part or piece of equipment to become very cold.

  • The accumulation of frost or ice inside the system might make the operation even more difficult.
  • Your air conditioner is blowing warm air.
  • Contrary to popular belief, allowing too much refrigerant to flow into the evaporator does not result in colder air being produced.
  • During the course of the system’s attempts to regulate the expansion valve or to cycle the compressor, the flow rate of the refrigerant might return to normal, at which point you may observe that the air temperature begins to fall once more.

Note any pools of water under your vehicle – this might indicate a freezing issue and can assist your technician in diagnosing the problem.

A Blown Fuse or Electrical Issue

The air conditioning system in your automobile is comprised of a maze of wires, switches, relays, and fuses. The electricity delivered to the A/C unit by these sections and parts under normal working conditions allows you to have cool air delivered on demand. If even one of these components fails, your air conditioner may shut down and begin spewing heated air. While this helps to avoid potentially deadly electrical fires, it also means that a simple, single blown fuse might force your entire air conditioning system to go off.

Help Us Diagnose Your Car’s A/C Problem

Take note of the following to assist our professionals in determining the source of the problem that is causing your A/C to blow cold then warm:

  • Is it all of the vents that are getting hot, or just one? How long had you been driving before the air conditioning began to blast warm air? Is this something that has happened previously, and if yes, how many times has it happened? What kind of driving circumstances are you in
  • Is it normal for the air conditioning to start spewing warm air when driving down the highway? When you’re stuck in stop-and-go traffic

Caravan blows cold air

In response to a problem where a Caravan blasts chilly air regardless of the temperature setting, Chrysler has released a service bulletin24-001-16 H. The advisory pertains to Dodge Grand Caravans and Chrysler Town and Country vans manufactured between 2011 and 2014, and it addresses the issue of cold air being blown by the Grand Caravan and Chrysler Town and Country HVAC systems. The fix is a software update that corrects a problem in which the HVAC system periodically blasts cold air regardless of the temperature selected by the vehicle’s driver.

Grand Caravan service bulletin applications

The service advisory is only applicable to cars manufactured on or before January 13, 2014 (MDH0113XX) and equipped with a Dual Zone Manual Temperature Control System (sales code HAD) or a 3 Zone Manual Temperature Control System (sales code HAD) or both (sales code HAK).

Cause of Caravan blowing cold air

It is NOT necessary to change any parts in order to resolve this issue. Chrysler has released fresh HVAC system software in order to solve the issue. Installing the updated software requires that you go to the dealer or an independent repair facility that has reprogramming capability. Except if your vehicle is still protected under the 3-year manufacturer warranty or if you have an extended warranty that includes coverage for the HVAC system, this is NOT a complimentary repair. Following the installation of the new software, the shop will execute an HVAC recalibration operation.

2006 Dodge Grand Caravan – Rear blower won’t blow hot air, only cold

Even though the setting on my 2006 Dodge Grand Caravan’s rear blower is set to ‘HOT,’ the air does not blast through the vents.

Ventilation will be activated if the temperature setting is changed to ‘COLD.’ This is true for both the control in the front and the control in the back of the vehicle. What might be the source of this problem? What should I do to figure this out? asked Posted on October 26, 2016 at 14:305

  • It is possible that there is a blockage in or around the rear heater core. If so, when was the last time the cooling system was flushed? Consider taking a peek at this blog article. It could be of use to you. Because I have no idea what is wrong with your van, I’m merely publishing this as a remark for the time being. Oct. 26, 2016, 14:59 p.m. The quantity of air that comes out of the vents is the problem – when the heat is turned up to the maximum level, there is no air flow in the vents, but when the heat is turned down to the lowest setting, there is normal air flow in the vents again. I’m not sure how a clog in the heater core might have an impact on the air flow via the vents, to be honest. Posted on October 26, 2016, at 18:48 You said that ‘hot air will not be blown via the vents.’ I assumed that to mean that the air was flowing out, although it wasn’t particularly hot. In other words, you’re saying that it ‘will not blast air through the vents when the thermostat is set to heat.’ Did you have a look at the link I provided in my comment? The response contains some useful information regarding inspecting and resetting the system. At 20:00 on October 26, 2016, Ugh – yep, I’m exhausted today – I made a clerical error in the original and will amend it. Anyway, yeah, I did go to the URL you provided. I’ll try if I can get it to work using those suggestions. Thanks. Posted on October 26, 2016 at 20:35 I followed the instructions in that thread, but I had no luck getting it to perform the ‘A/C Heater Control Calibration’ – it did the blinking of the lights, but they stopped blinking and went off in under 2 minutes. When the temperature is set to heat, the outcome is the same: no air is forced through the vents (which are located above the head). Oct. 31, 2016, 13:54 p.m.

2001 grand caravan blows cold air on passenger seat- driver and back hot

Okay, I know this is an old post, but I wanted to ask some clarifying questions in order to attempt to resolve my own problem. I have a 2006 TownCountry with dual zone heat, but it is not the fancy computerized sort with thermostats and such such gizmos. If I want more heat, I just move the temperature selector to the hot side of the dial. In any case, now that the weather has turned chilly around here (20 degrees), I’ve discovered that the air conditioning is blasting ice cold air at my shins while I’m in the driver’s seat, regardless of whatever vent or temperature setting I use.

The drivers side face-vents (for want of a better description) as well as the windshield vents are blowing scalding hot air at me.

When I first read this topic, I assumed the answer was the mix doors.

Is there a typical spot in the cabin where chilly air might make its way into the cabin around my feet that I should be aware of?

Car Heater Blowing Cold Air? Check the Blend Door Actuator

Mr. Fix-It-Up-For-The-Family When you turn on the fan in your automobile, does the heater just blast chilly air at you? It might be anything as easy as recalibrating the heating system or replacing the actuator that is the problem. We’ll show you how to do it.

Why is my car heater blowing cold air? Find the blend door actuator

What is the location of the blend door actuator? To locate and replace the door actuator, remove the glove box and under-dash trim panels from the vehicle.

Test the door shaft

Remove the screws from the blend door actuator and raise it out of the way. Check to verify if the door opens and shuts smoothly by twisting the door shaft or rotating the linkage.

Car not blowing hot air?

Modern automobiles employ electric motors (known as actuators) to regulate the temperature and direction of airflow by opening and shutting flaps in the heater box located beneath the dashboard. The most likely cause of your inability to modify the air temperature is that your battery has died or that you have unplugged it while working on your car. A simple recalibration will usually solve the problem. Find the technique in a shop handbook (which may be purchased for approximately $20 at auto parts stores).

  • The majority of the time, you can identify and repair the problem yourself in within an hour.
  • It only need a shop manual, a 1/4-inch drive socket set, and a few screwdrivers to get started.
  • In order to determine which actuators operate the defrost-vent-floor ‘mode door’ and the temperature-regulating ‘blend door,’ refer to the maintenance manual for assistance.
  • Allow a buddy to alternate between modes or temperatures while you keep an eye on the actuator.
  • There’s a possible that the mode or blend door actuator is in fine working order but that the door or linkage is stuck, so check that first before replacing the actuator (photo above).

However, if it is operating well, you should consider purchasing a new blend door actuator from the dealer or an auto parts store. Install it and run it through its paces to see how it works. In certain circumstances, you’ll have to run a calibration procedure on the device.

Required Tools for this Project

Make a list of all of the equipment you’ll need for this DIY project before you begin; you’ll save both time and frustration this way. An additional screwdriver with a flat blade as well as a Phillips-head screwdriver will be required.

Dodge Grand Caravan AC not working – causes and how to fix it

The air conditioning is a godsend, especially when the weather is hot and humid. Do you still get hot under the collar of your Dodge Grand Caravan when you’re driving? Is your air conditioning system no longer providing adequate cooling? This can be caused by a variety of factors. In this post, we will explain what they are and what you can do to prevent them. Grand Caravan from Dodge – (photo by Dodge) Some of the most common issues that can prevent your Dodge Grand Caravan’s air conditioning system from functioning properly include a dirty cabin air filter, a refrigerant leak, an unclean or clogged condenser, an unclean or clogged evaporator, a bad blower motor, a defective compressor, a faulty blend door actuator, or any other problem with the electrical system.

1. Dirty cabin air filter

The pollen filter, also known as the cabin filter or microfilter, is a critical component of the ventilation system in your Dodge Grand Caravan. It is located in the cabin of the vehicle. An unclean filter degrades the overall ventilation of the interior, resulting in decreased cooling, heating, and air movement. It also places an unnecessary strain on the entire air conditioning system, which has a negative impact on the fuel economy of your Grand Caravan. Although there is no set time for changing the cabin air filter, most manufacturers recommend that it be done every 10,000 to 20,000 miles on the road.

Inspect the cabin air filter in your Grand Caravan to see if it is in good working order.

This can be accomplished, for example, through the use of a vacuum cleaner or a compressed air system, which will remove at least a large portion of the visible debris.

As a result, even after cleaning, the filter performance will not considerably improve.

Video: Replacing cabin air filter in Dodge Grand Caravan

It is not necessary to take your Grand Caravan to a workshop in order to clean or replace the pollen filter. Following a few easy steps, as seen in the video, you may gain access to the filter. Note: A dirty cabin air filter almost always results in a reduction in cooling. If the only thing that comes out of your Grand Caravan’s air vents is hot air, the fault is most likely someplace else.

2. Dirty or clogged condenser

The air conditioning condenser on the Dodge Grand Caravan, like the radiator, is located at the front of the vehicle and is responsible for releasing the heat generated by the refrigerant into the surrounding ambient air. Grime, bugs, and other microscopic particles can accumulate on its surface and in the spaces between the meshes of its meshes over time. As a result, the condenser’s capacity to release heat is impaired since less air travels through the mesh, resulting in insufficient cooling in the interior.

In order to obtain access to the condenser, it is customary to remove the front bumper of the vehicle.

Air conditioning that does not function correctly on your Grand Caravan may be caused by a clogged or leaky condenser, among other things.

It is necessary to conduct a leak search within the air conditioning system in order to discover any leaks.

Forming gas is used in this process, and even the tiniest breaches may be found. It will be possible to determine whether the loss of refrigerant is caused by a faulty condenser in this manner. If this is the case, the only solution available is to replace the damaged component(s).

3. Refrigerant Leak

Inadequate refrigerant levels are still the most common reason of a non-functioning air conditioning system. Because of the design, it is usual for up to 15 percent of the refrigerant to be lost each year. If you don’t get your Grand Caravan’s cooling system serviced on a regular basis, the refrigerant level will ultimately drop to the point where the system no longer has enough cooling capability. Simply get it refilled, and you’ll be able to drive in comfortable temps once more. If the refrigerant level drops fast and then rises again, this indicates that there is most likely a leak.

Among the most prevalent reasons for condenser failure are worn lines, faulty sealing rings, and condensers that have been damaged by a stone chip.

In the workshop, the system is filled with forming gas (nitrogen mixed with a little amount of hydrogen).

Smaller holes must be located by scanning all components using a gas detector to determine their location.

4. Dirty evaporator

A dirty evaporator might possibly be the source of your Dodge Grand Caravan’s air conditioning difficulties. Even though the cabin air filter absorbs the vast majority of dirt and other airborne particles, some escape and land on the evaporator. Over time, these dust particles might accumulate on the fins of the evaporator, obstructing air movement through the evaporator and resulting in inadequate cooling. The following are the two most noticeable indications of a blocked evaporator in your Grand Caravan: 1.

  • Rather than being smooth, the air flow from the vents is turbulent. The interior of the vehicle is starting to smell moldy
  • This is a terrible sign.

Maintaining the evaporator on a Grand Caravan is not a straightforward process. In most situations, you will need to remove the whole dashboard in order to gain access to the evaporative cooler. As a result, it is advised that this be done in a workshop. It is also possible that a refrigerant leak has occurred in the evaporator, in which case the evaporator will need to be replaced.

5. Compressor failure

The compressor is at the core of the Dodge Grand Caravan’s complete air conditioning system, and it is the most expensive component. In order to cool your car, it has a cooling system that comprises of moving elements that transform what is essentially a gaseous coolant into a liquid. In most cases, a damaged compressor cannot be repaired. If the air conditioning is turned on and off on a frequent basis, the parts will stay mobile as well. However, if you don’t switch on the air conditioning in your Grand Caravan for an extended period of time, the pieces will become stuck together and become unusable.

The only thing that can be done is to change out the old one for a new one.

If you just replace the compressor in this location, another failure is unavoidable since the chips will instantly ruin the newly installed component.

Here, the metal pipes may be washed to the greatest extent possible.

During operation, however, the high-pressure refrigerant draws these chips back with it, resulting in the inevitable next harm.

6. Bad blower motor

If your Dodge Grand Caravan’s vents are not blowing air or are blowing air at a decreased rate, a faulty blower motor might be the source of the problem. When a blower motor is worn out or weakened, it can also make unusual noises when it is in operation. A faulty blower motor cannot be repaired; instead, the component must be replaced with a new one. It is important to note that if the blower motor fails suddenly, from one second to the next, you must first determine whether a blown fuse is to blame for the failure.

7. Faulty blend door actuator

In your Grand Caravan, the blend door actuator is responsible for adjusting the air flow and temperature within the vehicle. When there is an issue with the temperature of the air conditioning system, it is possible that the blend door actuator is at fault. Symptoms of a failed blend door actuator on a Dodge Grand Caravan include a faint clicking sound that comes from beneath the dashboard on a regular basis. When you switch on the air conditioning or alter the temperature, the sound will be the most noticeable for a few seconds after you do.

It’s possible that a banging noise coming from your Grand Caravan is caused by a defective blend door actuator, albeit this is an uncommon occurrence.

Conclusion

There are a variety of reasons why the air conditioning in your Dodge Grand Caravan may not be functioning correctly. When trying to figure out what’s wrong, it’s always best to start with the most obvious problem, which is a low refrigerant level in the system. In any case, it is recommended that non-technical people attend a workshop. In the case of a malfunction, the mechanic can immediately begin the repair process.
