Jeep A/C

barneyrubbleJune 4, 2007

I have a '97 Jeep Grand Cherokee 4.0. The A/C worked fine last season after recharging. When I tried it this spring, nothing but warm air. The refrigerant pressure is fine. Are there any simple (cheap) things I can check before having a shop look at it? Thanks!

Is the compressor engaging and turning?? If the clutch is not engaging use a jumper wire to short across the low pressure switch this should engage the compressor, now check for cool air. If you have cool air replace the low pressure switch if no cool air and compressor is turning you will need a real set of gauges to check the low and high side pressures while the compressor is running to determine your problem.
