early 1993 850GLT Air Conditioning Problems Topic is solved

[ecgreg]

Hello,

I have an early 1993 Volvo 850GLT with 185K. When I turn the A/C on the compressor kicks in for a second then kicks off again. I put a pressure tester on the low pressure port and it looks like the compressor kicks in at 25 psi and off again at 45 psi. I was told by local Volvo service people that the recycling of the compressor is usually due to low "freon" levels, but that doesn't seem to be the case here. Any one have any ideas? Bad sensor? A/C relay? Over pressure in the system? My wife drives the car about 300 miles a week and I'd like for her to have some A/C due to the high humidity.

Thanks!
