Jeep Cherokee Ac Compressor
Troubleshooting Your Jeep Cherokee AC Compressor
Even if you enjoy the great outdoors a lot, you have to agree that there's nothing quite like driving your Jeep Cherokee on a hot summer's day with the air conditioner on full blast. But, it won't be quite as delightful when your AC's compressor stops working. This hardworking component is supposed to take in the refrigerant fluid and cram its molecules together. This compression process transforms the cool, low-pressure liquid into a hot, high-pressure gas that then travels to the rest of your AC's parts to be cooled down and circulated through your cabin. When your Jeep Cherokee AC compressor fails, you'll need to find out why this happened and what you can do about it.
Leaking refrigerant fluids
Because the hoses that link your AC's parts together have microscopic pores, it's only natural that some of the refrigerant fluid seeps out. But, as your Jeep Cherokee gets older, a lot more fluid can leak out. When this happens, your compressor won't have enough liquid to work with, so it stops working. This AC component might even have a low-pressure safety switch that will automatically shut it down to prevent further damage caused by a lack of lubrication.
To find out if your compressor problems are caused by a leaking refrigerant, you'll need to add a refrigerant that's been pre-mixed with a special dye to your AC system. Just turn your Jeep's air conditioner on after your add the dye to let it circulate, then spray some soapy water on your AC's components. The dye will show where the leaks are so you can patch them up.
Compressor clutch not engaging
One of the most common reasons why AC compressors stop working is a magnetic clutch that has failed to engage. This can be caused by a blown fuse, a wiring problem, or something much worse.
To fix this, you'll need to start by replacing the AC's fuse. Afterwards, you should find out why it has blown in the first place to prevent it from happening again. Then, try checking your condenser's wires for any voltage problems. If you see that the clutch is receiving voltage but it isn't engaging the compressor, then the clutch is defective and it needs to be replaced. However, if you hear the drive belt squeal even if the clutch works, then your compressor has seized up. You'll need to replace it with a new unit immediately.
