Of course, Jeep enthusiast community forums, like Cherokee Forum, are great sources to find out what other Cherokee owners are saying about their A/C issues and how to resolve them.

The website It Still Runs did a great job of highlighting common issues to look for should you experience A/C problems in your Jeep Cherokee. The five-step approach should have you feeling the cool air soon.

Plus, we share other options below so you can enjoy the coolest summer ever in your Jeep Cherokee.

If you have a Jeep Cherokee, Compass, or Renegade and your air conditioning does not work, YouTuber host of World Mechanics shares "seven reasons why your A/C doesn't work."

"If your A/C does not work and blows hot air instead of cold air on a Jeep Cherokee, Compass, or Renegade with a 2.4 multiair engine, we will explain what can cause that and how to fix it," he promises in the clip before getting his hands dirty getting the project done.

"It is very frustrating to find out that your A/C does not work or blows hot air, and you do not know where to start and how to fix that problem.

"Reason number one," he continues, "is being low on freon. If the vehicle is older than eight years old or so, even six years old, I've seen that happen. Or the compressor can develop a leak, or maybe the lines have opened seals that can develop a slow leak over time, so that needs to be addressed."

Check out the World Mechanic video above to see the other six tips he shares to help fix your Cherokee's air conditioning problem.

In YouTuber OmegaGreed's  video titled "Jeep Grand Cherokee AC Fix Fail," OG is trying to fix his 2005 Jeep Grand Cherokee's air conditioning, which has stopped working.

It's something he expected was coming when he bought the used car, but he's not going to let it stop him from enjoying the car. And he's sharing how he resolved the problem of his Cherokee's air conditioning blowing out warm air…

"The whole reason why I got this vehicle for so cheap is because there were a couple things that were going on with it," says the host, who also runs the Geeks with Cars blog. "One: The A/C is basically out. It's pumping out like super-lukewarm air…"

Whether he was successful or not is in question even by the video host. But the process he runs through is what you need to know to recharge your Cherokee A/C system. And he says he did the project for around $40.

"I went and bought a new A/C refrigerant fixer for the AC compression in the Jeep but it didn't seem to fix my issues," he explains.

"It seems as if the AC had pressure in it already. I added more AC refrigerant to the car AC system but that didn't seem to work either. It was worth a try, now that I know that didn't work I'm checking the fuses in the car along with seeing if I had a leak somewhere in the system."

How Does the Jeep Cherokee Air Conditioning System Work?

Air conditioning systems in vehicles have many working parts, and it's key that all of these parts work together to create a seamless, comfortable air conditioning experience for the driver and passengers.

Take a look at how a vehicle's air conditioning system functions in this video by AC Avalanche.

Many problems with vehicle air conditioning systems are due to leaks, and they can be fixed easily. Clogged tubes and failed air conditioning blower motors can also be at fault. Now, we'll take a look at the common issues that drivers have with their Jeep Cherokee air conditioning systems.

5 Common Problems with the Jeep Cherokee Air Conditioning System

1. Faulty Cooling Fans

Some Jeep Cherokee owners mention that the system does not blow air efficiently. This is often related to a faulty cooling fan. A mechanic can inspect the AC system and replace the cooling fan to solve the problem.

2. AC Settings Continually Reset

Some drivers have experienced their Jeep Cherokee air conditioning settings resetting randomly. For most drivers, this is simply an annoyance. A mechanic can inspect the air conditioning and electrical systems and replace responsible components. The National Highway Traffic Safety Administration (NHTSA) Complaint ID for this problem is 11286884.

3. AC System Interacts Inappropriately with Electrical Components

Some Cherokee owners have reported that when the air conditioning is on, electrical aspects of the vehicle fail to work correctly. A few complaints state that all of the gears on the shifter light up at the same time, while others report that the vehicle's infotainment system malfunctions.

While this issue may simply be an annoyance, both issues can be distracting. The distraction can cause the driver to lose focus on the road, which can increase the likelihood of a crash.

For this issue to be fixed, it's essential for a mechanic to inspect both the A/C and the electrical system to find the root cause of the problem. The NHTSA Complaint ID for this issue is 11208641.

4. Air Conditioning Suction/ Discharge Hose May Split

This issue can cause a sudden loss of air conditioning while the vehicle is in motion. Jeep issued a recall for some vehicles that experienced this problem, but some vehicle owners whose VIN was not included in the recall have experienced this issue as well.

To fix this issue, your mechanic can inspect the air conditioning system and replace the suction/discharge hose if necessary. The NHTSA Complaint ID is 11207299.

5. Mold Odor Coming from AC System

Some Jeep Cherokee owners notice a mold odor coming from the HVAC system whenever the air conditioning or heating components are activated. While this is likely not a safety issue, it's an unpleasant problem that needs to be fixed.

A mechanic can dismantle the AC system and find the source of the odor to fix the problem. The NHTSA Complaint ID is 10926205.

Frequently Asked Questions

Sep 20, 2021

Why is my Jeep Cherokee AC not working?

When the air conditioning is not working in your Jeep Cherokee the first thing that you should do is make sure that there are not any electrical problems. These are the easiest to fix since you can usually fix the electrical issues by resetting the A/C controls on the dash, or removing and replacing the fuse.

If there are not any electrical problems then the next thing to check is for a refrigerant leak in the A/C system. You can check for a leak by using a meter to see if the refrigerant lines are properly charged. If you notice that your refrigerant levels are low then you can use a UV-based dye to find the location of the leak.

The final thing that you should check is the A/C compressor. This is on the accessory drive belt and if there are issues with the compressor it will not compress the refrigerant to send it through the system. This results in the A/C blowing hot air.

What would cause my car air conditioner to stop working suddenly?

If the A/C in your Jeep Cherokee stops working suddenly then the first thing that I would suggest checking are the fuses for the A/C system and the fans. If one of these has blown then the fans will not work and you will get no airflow from your A/C system. These are also the easiest to replace since usually you just need a new fuse and then your system will work again.

Another thing to check if your A/C stops working all of a sudden is the accessory drive belt. These are a consumable part that has been known to wear out, and when they do they will not drive the compressor and you will lose all air conditioning cooling capacity with no warning.

Typically one of these two things is the issue in a Jeep Cherokee, usually, if there are leaks or the compressor is failing you will notice a gradual decline in cooling performance instead of it just stopping all of a sudden.

How do you turn on the AC in a Jeep Cherokee?

Turning on the air conditioning in a Jeep Cherokee is a pretty straightforward process, for many of the newer model years Jeep has moved the controls to the touch screen in the dash. First, you will need to go to the screen and get to the home menu where you can press "Climate" which is located at the bottom of the screen.

Once you are in the climate menu you will have a series of icons on the screen and you can adjust the A/C as you like. Make sure that the A/C icon at the top of the screen is illuminated to confirm the system is on. Next select where you would like the air to blow from using the icons in the middle of the screen. After that, you can use the slider on the left side to control the temperature for the driver, and the slider on the right side for the passenger.

Jeep has moved to have climate control settings in their infotainment system which is a departure from the classic way of having buttons on the dash. It can be a bit different, but the icons and buttons both do the same things.
