Was towing some scrap to the yard and went to flip my a/c on an I got no delicious cold breeze... bummer just had a new pump put on and recharge

Well have after investigating, I still have a charge, but the clutch is not being energized. I still need to check the a/c fuse to see if its blown. But does anyone have a diagram of the a/c circuit? its a 1990 f350 crew cab idi 7.3 2wd. Thanks hope to get my freeze box working again before the weekends out got more scrap to haul.

pm me your email address and i'll send you the ones I have for a '95.

are you getting voltage and the clutch is not engaging or is there no voltage to the compressor?
