I have a 93 tempo. The A/C was low on refrigerant, the compressor was still coming on but the air was only cool. Later in the week I got a chance to evacuate and charge the system. By this time the compressor was no longer coming on. I pulled out .23 lbs of R134A and put back in 2.04 lbs. of R134A. The compressor still will not come on. I did nothing else to the car other than charge the system. I checked the fuse, it is good. Anyone have any idea why the compressor will not come on with a charged system? The compressor is not locked up, I can still turn it by hand. Thanks.
