2002 Jeep Grand Cherokee A/C Problem - Please help

My wife and I had dinner with an elderly neighbor tonight. She mentioned the heat (100 +) and the fact that her 2002 Grand Cherokee has not had working A/C for 3 years. During this time, she has paid over $3000 to have it fixed/serviced. Longest that it has worked is 1 week.

She has had the condenser, dryer and evaporator replaced. Also the high and low pressure safety switches. Also the dash controls. She has been to A/C specialty shops and dealerships. She has written Jeep and spoken to regional reps, all with no solution.

I looked at the car tonight. The car starts and idles fine. The belt is intact and turns fine. The 15A fuse under the hood is good. The dash switches and lights are functioning. The fan blows and its controls work the fan pressure. Not sure about the clutch relay. The clutch is not engaging and the compressor is not turning, even for a moment. There doesn't seem to be any voltage to the compressor clutch.

Any ideas? And why hasn't anyone been able or chosen to fix it?

Please help as this is an elderly women who doesn't need this?

may not have any refrigerant in it. beg or borrow a set of a/c gauges + post back. some of the really smart folks (not me) on here can help you diagnose it.

Good Luck 2 ya,

65% of mobile a/c failures are due to loss of refrigerant due to a leak--- play the odds- find and fix leak

Get a set of gages on it as suggested...

The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......

I agree the first step is to find out if there is refrigerant in the system, static pressure along with ambient temp would be a start, could be as simple as a cycling switch, or something major, more information is needed, but it should have been fixed by now...
