'96 Pontiac Sunfire, identical to the Cavalier.

I replaced the A/C compressor, reloaded the oil and R134A, but I don't get power to the compressor, even though the A/C lights are on in the A/C positions. The unit is loaded and works if I hot wire the compressor, but there's no power on the connector end (measures 0.05V)
Here's my original post over in the Pontiac Forum

Any suggestions?

Bad Switch?

Found the problem.

The fuse block on the fender wall had a broken pin-contact on the relay.
I put a piece of bare copper wire in it to make contact with the relay pin and the compressure now works.
