How Does a Truck’s Air conditioning System Work?

Air conditioning in your car is a system meant to reduce heat inside the vehicle. But for it to work, it needs the compressor.

Simply put, the compressor powers the air conditioning system. You could think of it as the workhorse of the AC system.

This compressor receives low-pressure gas, which is then turned into a high-pressure gas.

That gas then flows into your car’s condenser. Once that gas is sent to the condenser, it’ll cool down the high-pressure gas and then turn it into a high-pressure liquid.

After that, the liquid flows into the receiver dryer. This receiver will screen out any impurity.

Next up, the liquid goes to the expansion valve, which is then converted into a low-pressure liquid.

From there, the low-pressure liquid flows into the evaporator, which then begins to evaporate.

After a while, it is then converted into a low-pressure gas. Finally, the blower motor pushes the air through your truck’s dashboard.

Common Dodge Ram Air Conditioning Issues

Knowing how to fix any air conditioning problem is a great skill to have.

That being said, check out these common issues to fix your truck’s air conditioning system:

1. Blown Fuse

It’s like you can’t catch a break, you’re just trying to get in your truck and go to work, but your air conditioning can’t do its job.

But as terrifying and frustrating as this problem might seem, you might be able to fix this problem by swapping out the AC fuse.

If you’re not quite sure what that means, let’s just say that the air conditioning needs that fuse to work.

Also, If the fuse quits working, you’ll hear a humming sound as soon as you turn on the air conditioning, and it won’t get cooler.

With that out of the way, here’s how to tell if the fuse went out of service:

  • Pop the hood of your Dodge Ram. After that, open up the fuse box. If you take a closer look, you’ll find the diagram. Follow that chart, and find the F 62 AC clutch and then take it off.
  • After pulling out the fuse, take a look closer at the metal chip inside. If there’s no break in the connection, then you got a healthy fuse. But if it’s broken inside, please replace the fuse.

It’s insane how common this problem is on the Dodge Ram and many other trucks. But remember, always check the AC fuse before throwing parts at your vehicle.

2. Cold Air Is Not Blowing At All

Dodge Ram air conditioner problems can indeed be problematic. There’s just so much that could’ve gone wrong, making it hard to tell on the spot.

Some people just roll with it, while others can’t help it but feel frustrated.

So what is wrong with my vehicle? Well, the AC evaporator might have passed away.

You see, the radiator is inside your truck has a simple yet crucial job, which is to provide cold air for the AC system.

But if it quits working, the AC won’t blow any cold air. This is pretty common, and it might very well be your case.

Usually, the AC evaporator leaks are caused by corrosion. When it gets corrupted, the seals inside will eventually break, causing a leak.

Nonetheless, here’s a small summary of some of the most common problems related to the AC evaporator:

  • If the evaporator is leaking, you might smell a sweet but somewhat off-putting odor coming from your air conditioning system.
  • When the AC evaporator is leaking, the temperature will fluctuate. However, this could also mean that it went out of service and must be replaced.

Replacing the AC evaporator is somewhat challenging and can take some time if you’ve never done it before. However, if you want to save up some money, here’s a useful video for this job:

3. Evaporator Got Clogged

Another common Dodge Ram 1500 air conditioning problem is that the AC will work, but after some time, it’ll get hotter, and then the temperature will drop, and so on.

In many cases, a drop in temperature is related to some restriction inside the system.

But unless you’re some superhuman, you won’t be able to see through your vehicle and find what’s wrong with it.

So, you’ll have to use a ray tech heat gun to see through the air conditioning system.

But if you don’t have one of those fancy tools lying around, get an infrared LED light pen. It’s pretty cheap, and you can find one for $20.

That said, if you want to follow along with this short tutorial, get a ray tech heat gun and follow these steps:

  • Remove the grill and then take different temperature readings to find the problem.
  • First, take the inlet temperature and then the outlet temperature. When doing this, keep in mind that the inlet temperature must be hotter than the outlet.
  • If the inlet temperature is higher than the outlet, you know that the condenser is getting rid of heat.
  • But since the condenser doesn’t always work, check various points. When doing this, you could get 120 degrees on one side, and right next to it, you could get 82 degrees.
  • This means that the hot fluid is flowing through, but somewhere in the system, there’s a blockage, so there’s no hot fluid flowing through.

If you’ve successfully determined that the condenser got blocked, then you’ll have to replace the whole thing.

4. Noisy Blower Motor

I fear no man, but a noisy blower motor can genuinely be terrifying. Seriously, hearing any noise coming from the vehicle can be pretty creepy. You can only ask yourself what went wrong with the car.

Anyway, this happens every time you turn on the air conditioning system. The blower motor causes the noise.

Usually, some leaves or debris got stuck inside the blower motor. So, when you turn it on, the engine hits those leaves, making some noise.

But in other cases, if the fan stops working, that’s usually a clear sign that the blower motor went bad and must be replaced.

Don’t worry, though. Replacing the blower motor is super easy and barely takes any time. Anybody can pull this off.

That said, if you’re down for this job, here’s how to do it:

  • On the passenger’s side, where your feet would be sitting, you should be able to see the blower motor. To remove the fan, please use a T20 Torx driver and an 8mm socket.
  • After pulling it out, remove the wire holding it together. Be careful. You don’t want to deal with electrical issues. Once that’s done, grab the new one, put it in, and then feed the screws.
  • Finally, connect the wire.

In most cases, you’re better off getting a new blower motor. For example, you could get a brand new one for $40.

You might be able to repair the old one, but it’s not worth the trouble and effort when you could get a new one.

That said, if you want to learn how to clean the motor and replace it, here’s a well-made video for this job:

5. Vibration

Finally, Dodge Ram air conditioning vent problems may include but are not limited to vibration and lack of air.

Vibration and noise are two common problems found on the Dodge Ram. And most of the time, swapping out the blower motor solves the issue.

But if you’ve already replaced the motor and found nothing wrong with it, then you might have a damaged blend air door damper.

Luckily, for the low price of $30, you can find a replacement. But here’s the thing, it takes a lot of time to replace the blend air door damper.

You have to take off the dash, and then recharge the recover A/C, which takes a lot of effort and time. And if you take the vehicle to the dealer, expect to pay anywhere from $850 to $900.

6. Air Stops When Accelerating

Some of the problems related to the AC system can be hard to find. While you can fix the issue by changing the AC fuse in many cases, you might have a vacuum leak this time.

You can most of the time tell you got a vacuum leak when the air conditioning system stops working as soon as you step on the pedal.

Upon researching, we’ve noticed that Dodge Ram owners have expressed that it’s almost always the vacuum line attached to the cruise control.

This line is underneath the truck’s battery. After replacing the broken line, the AC should work again.

However, finding a vacuum leak takes a lot of time, but it’s not impossible if you’ve got some spare time.

That being said, here’s a well-explained video that will show you how to find a leak on your vehicle:

Dodge Ram AC Replacement Cost

It is pretty common to experience Dodge Ram air conditioning problems. And in many cases, you can fix it yourself.

But if you don’t feel confident about your mechanic skills or can’t be bothered to solve this problem on your own, then expect to pay $250 for a new compressor.

The labor cost for this job can range anywhere from $100 to $120.

However, depending on how bad your problem is, your mechanic might have to flush the evaporator along with all the lines since acid contaminated the system.

So, if that’s your case, expect to be quoted about $1,600 for this job.
