Every modern vehicle has an air conditioning system that regulates the temperature, so you don’t feel uncomfortable while driving. However, many users have complained of dodge ram air conditioning problems. This article will look at some common causes and solutions of air conditioning in a Dodge Ram.
Before we begin to diagnose common dodge ram air conditioning problems, it is important to understand how the air conditioning system works. For most users, all they do is press a button, and they get a blast of cold air, but the system’s inner workings can be a mystery. Well, not anymore!
Let’s take a closer look at the process. The AC system works by cycling a refrigerant or coolant, converting it from a gas to a liquid and back again. The most important part of the air conditioning system is the compressor. It powers the AC system by receiving low-pressure coolant into a high-pressure gas.
Increasing the pressure of the coolant increases its temperature, and this warmer gas is sent to the condenser. As the hot gas passes through the condenser, cool air flows over the condenser and cools the refrigerant. This causes the refrigerant to condense and becomes a high-pressure liquid at a lower temperature.
Next, the liquid is sent to the receiver/dryer. The dryer receives the high-pressure liquid and filters it by removing dirt, metal particles, and moisture. The dry liquid refrigerant flows to the expansion valve, which reduces the pressure and temperature of the refrigerant further, making it ready to cool the car’s interior.
The refrigerant then goes to the evaporator, which absorbs heat from the liquid refrigerant, reduces the temperature to about -32℃, and transforms it into a gas. As the gas cools, a fan blows air over the evaporator, causing the air to cool, and is blown into the car to keep it cool. From the evaporator, the low-pressure gas flows into the compressor to start the cycle all over again.
Now that you know the car AC system works, let’s examine some of the common dodge ram air conditioning problems.
If your Dodge Ram isn’t blowing any cold air while your air conditioner is on, it’s probably the evaporator that is faulty. This commonly happens when the evaporator gets corroded, which leads to the seals breaking, eventually causing it to fail to evaporate the coolant properly.
If you try to turn on the air conditioning in your Dodge Ram and it starts making weird noises, it could probably be your blower motor that has developed a fault. It could even just stop working, which will necessitate you replacing it.’
If the air conditioner in your Dodge Ram stops while you accelerate, it’s probably a vacuum leak at fault. Most Dodge Ram owners have said that it is usually a problem with the vacuum line attached to the cruise control.
If you’re hot, sweaty, and then try to turn on your Dodge Ram’s air conditioning, but it doesn’t come on, it can be caused by a problem with the AC fuse. One way to ascertain that the AC fuse has blown is that the air conditioning will produce a humming noise whenever it is turned on, but it won’t get cooler.
A common problem Dodge Ram users face is the AC vibrating excessively when turned on. Again, it is likely a fault with the blower motor. If you get the blower motor fixed and the problem persists, it could be caused by a damaged blend air door dampener. This is not an easy problem to fix, and getting it fixed at the mechanic’s could set you back by up to $1000.
If you have noticed any of these Dodge Ram air conditioning problems, you need to know how to fix them so that you don’t experience excessive heat when driving.
One way to fix this is to take your Dodge Ram to the mechanic, who will most likely replace the evaporator or the condenser.
It is pretty easy to replace a damaged blower motor. You just have to get in the passenger side and check where your feet would normally rest. Your blower motor should be right around there. (Use a T20 Torx driver and an 8mm socket to remove the fan.)
After you’ve pulled it out, carefully remove the connecting wire. Then, put in the new one, screw it in properly before connecting the wire you removed earlier.
You can take your car to the mechanic’s shop to fix the vacuum leak. It’s easier and safer than trying to do it yourself.
You should check your AC fuse first before trying anything else in the event of a faulty Dodge Ram air conditioner. Follow the instructions on your car manual to find the fuse and replace it if necessary.
Replacing the blend air door dampener is a long and tedious job, which you’re better off handing over to the mechanic. It is a bit costly, but at least you’ll have the assurance that it will be a job well done.
In many cases, a blown AC fuse causes the air conditioner to stop working. Go to the fuse box in your truck and check the fuse. If the fuse looks worn out, replace it, and your air conditioning system should work.
The condenser may have stopped working or become clogged if your air conditioner is still running but not cooling your truck. It will either need to be replaced, or the system will stop working.
It might be wise to roll down the windows and park in a shaded area if you are on a budget. It also keeps the interior of your car cool. Another solution is to spray some water and open the windows to allow the water to evaporate while the vehicle is in motion.
While a lack of proper air can be annoying, you can drive without the AC condenser. The choice is yours whether to drive with no cold air.
