A/C on a 2000 Cherokee
I have a 2000 Jeep Cherokee with about 120,000 miles. The Air
Conditioning has been acting strange lately. It will work for about 10-20 minutes and then it will start to blow luke warm. If I turn off the A/C for about 10 minutes, it will start back up for 10-20 more minutes. I took it in for service but I was told that they were not able to find a problem with the A/C. They emptied the AC then and re-filled it. They checked for leaks, charged the system, blah blah blah. Anyone have any ideas of something to check out? Thanks very much! |

I was hoping someone would tell me thast it was simply the thermostat or the engine was too hot or something along those lines. The engine temperature is why I brought up the coolant. It seems the AC has been acting funny ever since I had a blown coolant hose. It was replaced and the coolant was replenished (but more water than coolant). Anyone else have any comments? I'd like to bring a little bit of knowledge with me when I take the Jeep to a new shop. I would hate to get riped off. My normal mechanic, whom I trust not to rip me off, is the one who hasn't been able to fix the problem. Thanks ahead of time! |

going out on a limb but the system may be overcharged and freezing up
did you see them use a machine to recycle and recharge the system ?? wasntme wrote: > Bill Putney wrote: > > The engine coolant would not affect the a.c. operation.
