    got a 88 blazer s10 need help with ac prob
    ok ill make it quick and detailed as i can. ac system is charged, ac compressor is good. all fuses are fine i get power to all of the wires but once it gets to the relay nothing after that. i tried new relays nothin. the only way it works is if i use a wire to connect the power wire which in this case is the pink with black stripe and cross that to the green with black stripe. so power is getting to the relay in one wire but there are 5 there. need to know what to do to get this fixed asap.

    Have you checked you pressure switches? Do you ever go to George and Dragon II on 48th St?

    You need to put a jumper in the switch. Disconnect the switch and jump the plug. GMs AC systems are notorious for this.

    I just had something similar. Everything appeared to work fine but no AC. I found out the the compressor clutch was siezed.

    I was talking to him offline, and it was his Low pressure switch....
