When you’re driving, you don’t have to worry about overheating because your car has an air conditioning system. Many Ram owners, on the other hand, have expressed concerns about the vehicle’s air conditioning system. Having trouble with the air conditioning in your Dodge Ram? Read on to learn about some of the most frequent problems and how to fix them.

How Does a Dodge Ram’s Air Conditioning System Work?

Dodge Ram Air Conditioning Problems

We must first understand how the air conditioning system works before we can begin diagnosing typical Dodge ram AC problems. The system’s inner workings may be a mystery to most users, but all they have to do is press a button to get a blast of cool air. Not any longer, that is!

A closer look at the procedure is warranted. A refrigerant or coolant is cycled through the AC system, transforming from a gas to a liquid and then back again. The compressor is the most critical part of the air conditioning system. It converts low-pressure coolant into a high-pressure gas that powers the AC system.

The condenser receives the hotter gas as a result of the increased pressure in the coolant. Cool air flows over the condenser, cooling the refrigerant as it goes through. These conditions result in a high-pressure liquid at a lower temperature condensing the refrigerant, making it easier to remove.

The receiver/dryer is the next step in the process. Receives the high-pressure liquid and removes dirt, metal particles, and moisture with the dryer. Flowing through the expansion valve, the dry refrigerant cools the car’s interior by lowering the refrigerant’s pressure and temperature even more.

The liquid refrigerant is then sent to the evaporator, where it absorbs heat, cools to 32°C, and eventually turns into a gas. Air is blown into the car through the evaporator when the gas cools down, which cools the air. The low-pressure gas from the evaporator flows into the compressor to restart the cycle.

Knowing how the automotive air conditioning system works, we can look at some of the most typical issues that arise with a Dodge ram.

1. Cold Air Not Blowing At All

Your Dodge Ram’s evaporator may be faulty if the air conditioner doesn’t produce any cold air. When the evaporator is corroded, the seals break, preventing the coolant from evaporating properly, and this is the most prevalent cause of this problem.

2. Noisy Blower Motor

If your Dodge Ram’s air conditioner starts making strange noises when you try to switch it on, it’s likely that the blower motor has developed a defect. If it simply stops operating, you’ll have to buy a new one.

3. Air Stopping When Accelerating

If your Dodge Ram’s air conditioner shuts off while you’re accelerating, you’re probably dealing with a vacuum leak. Vacuum line to the cruise control is the most common cause of this problem, according to Dodge Ram owners.

4. Blown AC Fuse

AC fuses can malfunction if you’re hot and sweaty and try to turn on your Dodge Ram’s air conditioning and it doesn’t work. To determine that the AC fuse has blown, turn the air conditioner on and it won’t get any cooler, making a humming noise.

5. Vibration of the AC

When the AC is turned on, many Dodge Rams vibrate significantly. Again, the blower motor is most likely to blame. If the problem remains despite having the blower motor repaired, you may have a faulty blend air door dampener. This is not an easy problem to cure, and it could cost you up to $1000 to fix it at the mechanic.

To avoid driving in uncomfortable temperatures, if you’ve encountered any of these Dodge Ram air conditioning issues, you’ll want to learn how to fix them.

1. Cold Air Not Blowing At All

The evaporator or condenser may need to be replaced by a mechanic in order to address this problem.

2. Noisy Blower Motor

A broken blower motor can be easily replaced. Check where your feet regularly rest by getting into the passenger seat. You should be able to find your blower motor in this area. T20 Torx driver and an 8mm socket are needed to remove the fan from the motherboard

Carefully remove the connecting wire after you’ve taken it out with the pliers. Before connecting the wire you previously disconnected, replace the old one and screw it in firmly.

3. Air Stopping When Accelerating

The vacuum leak in your car might be repaired by taking it to a mechanic. You don’t have to risk your own safety by trying to do it on your own.

4. Blown AC Fuse

In the event of a faulty Dodge Ram air conditioner, you should check your AC fuse first before trying anything else. If you can’t find the fuse, see your owner’s manual for assistance.

5. Vibration of the AC

It’s best to leave the job of replacing the blend air door dampener to a professional. It’s a little pricey, but at least you can rest assured that the work will be done correctly.


Why Is My Truck AC Not Blowing Cold Air?

A blown AC fuse is the most common cause of a malfunctioning air conditioner. Take a look at the fuse in your truck’s fuse box. Your air conditioning system should operate if the fuse is replaced if it appears to be worn out.

Why Is My AC Running but Not Cooling in My Car?

If your air conditioner is still working, but your truck isn’t cooling, it’s possible that the condenser has failed or become clogged. In any case, it will need to be changed or the system will no longer function.

How Can I Keep My Car Cool Without AC?

To save money, you may want to open the windows and choose a shady spot to park your car. It also helps keep your car’s inside cool. While driving, sprinkle some water on the windshield and open the windows to let the water evaporate.

Can You Drive a Car Without an AC Condenser?

You can still drive without the AC condenser, despite the inconvenience. You have the option of driving without chilly air conditioning if you so desire.
