    My 1997 peterbilt 387 has good cab a/c but recently I began to try the sleeper a/c and not a link of cold, or hot for that matter, of air comes out. Like the blower is out or something. I looked at the fuse box relay and changed them out. Still nothing. Anyone got any ideas to what might be the problem with it? It's easy to hot in Phoenix to go without a/c.

    The only thing I can think of is freon. For now you are kind of screwed.

    Freon? Nope, just had it charged up. Besides, the From can ac works fine. The sleeper won't even blow any air at all

    Find a DVOM and track down where the power to the A/C stops, repair defect, and chill...

    Phoenix? Find a shady spot and just live with it. Maybe pretend you're in a sweat lodge, have a vision quest from heat stroke. Those crazy Phoenicians love that metaphysical crap.

    Find a 12Volt test light turn on fan switch and unplug wire going to blower fan in bunk CK. if you have power at plug, if no go back to switch to be sure power is geting to fan switch? this way is cheaper that buying ever part till you find the one that is broken, fan switch, fan motor,wiring,

    Thanx baha. After following through on what you said. Found the wires to the fan were corroded to the point that the ground wire was disconnected from the fan. Only a thread seemed to hold it together. Re wired it and it works fine now. Thanx again for all the replies
     
    baha Thanks this.
