Today The ac in my 93 Gmc Suburban is blowing hot air. I have never had this problem before. It has always blown cold. The compresser is not turning. checked fuses. all ok. Is there any relays or anything else ya'll can tell me to check. TY Spanky

With the a/c on and the truck running, jump the pressure switch and see if the comp turns on. I think it is located on the pass side on the dryer. Most trucks anyway.
