Air Conditioning not working, no apparent problems!

Here's the deal, Ive got a 95 GST and the A/C isnt working. Ive tested the compressor and it works fine, and all the fuses/relays are in working order as well. The system is at correct charge level. There is no power getting to the three wires that connect to the compressor or to the pressure switch. Ive tried switching the A/C switch on the HVAC control panel (which works, but nothing happens) and the resistor behind the glovebox. Im at wits end on this. Please help!

Check the wiring for breaks.

Could be the dreaded (ACCU) Automatic compressor control unit. From what I have heard they don't make that part anymore. So if it was indeed bad you will need to find a Junkyard car with the same control unit.

finding one is not a problem. ive got a salvage 98 GS and a 96 GST as well as some 1st gens. what is it and where is it located?

Its behind the glove box. Mounted to the AC unit. There is a small black box that says auto comp controller.

Here is a pic of both units that could be bad. they are both behind the glove box

OK, got problems...my car doesnt have or use the first unit pictured, and has a different ACC than pictured. I took an ACC off of a 95 Talon TSI (which i thought would be the same as a 95 Eclipse GST) but it is different and doesnt change anything when plugged in. I checked a 96 GST Spyder, which is also different, and uses the first unit pictured with different wiring than my car has, but has no ACC box. I also checked a 98 GS and it has a different ACC box and plug-ins that dont line up with my plugs. I couldnt locate either in a 94 GS. Im still getting nowhere. Every car I checked today has a different setup than mine. Any ideas?
