Yes I checked every fuse in both boxes. But I did find two burnt fuses one to the ignition which confused me because it still started so how was a ignition fuse bad and it started fine? If the switch is bad will the one from my 87 work?

When I said I checked every fuse I should have said I pulled every fuse and checked them with a multi meter. I also checked every relay with the tester I made. It is a relay socket off the 87 with a switch to 12v and a ohms reader across the relay.

With the dash switch set to A/C and ignition "ON" do you have 12v @ the compressor clutch & blower motor? If not start with the dash switch/connector.

Ok so key on and controls set to A/C max and blower turned to high. No 12v at A/C clutch or fan wires. fan checks out so blower is still good thank god.
