ok i have been trying to get my a.c. working. p.o. has changed two relays with aftermarket ones.one is for the starting . i have traced the blue wire from the compressor to a square relay on the firewall so i believe he hasnt touched that one.my problem is no power to anything in the ac system.fuses all good and checked in car and under hood.all other elec systems in fine working order. p.o. had a jumper from fuse box to ac switch and that would make the blower work but not the compressor.my wiring diagram does not show the ac system so i am kinda shooting in the dark here.when p.o. installed the relay for the starter there are 4 wires that he left loose .2 brown with white stripe and two larger black wires. i understand that when starting car with the ac on it will turn off the ac relay to aide in starting .could it be that one of the loose wires be a power/ground wire for the ac system? also does anyone have a old wire harness that i could buy or at least the sockets and relays w/pigtail so i can match the wires up.or even send me a pic of the relays and wires from your car to help me see what goes where? please guys and gals feelin kinda left out of the cold here.

I have a 108 chassis 2.5L six. If you have a 108, I can provide some digitals of my AC wiring if that helps you. It sounds like whatever is wrong is common between the blower and compressor clutch coil, which might actually make it easier to fix.

digitals would be great THANKS
