Also check your high pressure switch. My car would shut down the A/C after a while. Jumpered the HP switch and all is well. Turned out to be just a bit overfilled, and that would drive the pressure up just a little too much. Readjusted and all is well again.

Fellow Listers --

A/C compressor will not engage - jumpered relay compressor runs - suction pressure is good - A/C cools well -- I suspected the relay - tried 2 different relays from the salvage yard, compressor will not start - seems unlikely, although not impossible that 3 relays would have failed in the same manner.
Prior to the start of this problem there were times when the A/C - Climate Control would seem to get lost and stay in heating when cabin temps were above setpoint and vice versa. Is it possible that my problems are caused by the cabin temp sensor, the circulating fan for this sensor is functioning properly? What other possible sources for this/these problems should I be investigating? Any help will be greatly appreciated.
Thanks in Advance
