After I swapped the motor on my coupe, my AC isn't working. I just put another Z6 in it, so it's the same AC I had before. It was working fine before the swap.

I have tried to trace all the wires and everything looks hooked up. But maybe I am missing something. The compressor isn't kicking on. The fan on the radiator is the only that comes on when I turn it on.

Any ideas? Car is 94 Civic Ex Coupe.
