Hey Guys, I have a 1999 Cherokee Sport with the 4.0L, and I seem to be having some a/c problems. When I first crank the Jeep, and the engine is cool, the a/c works flawelessly. The compressor stays engaged until you turn the system off, which is where my problem begins. I have noticed that when the system is running, the compressor does not cycle off, the fans and the compressor stay engaged until you turn the selector off. After the engine has warmed and you have ran the system for awhile, and turn it off, and then attempt to turn it back on, the fan starts running, but the compressor does not engage. I know that the system is fully charged due to buying a pressure gauge to test the pressure. Any thoughts on the compressor not reengaging after turning the system off? I am wondering if maybe one of the pressure sensors is going bad or is their a compressor cycling switch on this car? Any help or thoughts is greatly appreciated!
