Question A/C problem

I own a 99 Ford Escort with an electrical problem with the A/C. The system is fully charged, no leaks detected. I have power at the low pressure switch above the can, but no power at the clutch. I can bypass the wiring and get the a/c to work if I add power directly to the clutch. Where else should I look? All fuses seem to check out.

That car has an integrated sealed relay box that houses the compressor relay and the cooling fan relay and they fail quite often. They put them in different locations. Sometimes they're near the left headlight and some are behind the glove box. It's about 5"long, 3"wide and 2" thick. It has a flat wire connecter attached with an 8mm head bolt in the center of the plug with close to a dozen wires.

Thanks for the response. Sounds like a lot of fun. A remember finding a lot of things with numberous wires coming out of them. That is when I decided to start asking around..try and narrow my choices. So is this relay a typical relay where one can find the hot wire and bypass the relay to see if it is the problem? I know the cooling fan works.

No, it's not very typical at all. It's solid state and very difficult to verify input. You could find the output wire and test it but that won't tell you anything you don't already know.
