AC Issues - Suggestions needed ASAP

[rundle]

Okay - here is some vital inforamtion that was left out of earlier posts! Went back and did some more questioning....

Everything works great - cold air and etc - when hard wire to the compressor (thus the pressure and etc being correct) and the compressor clutch kicks in and everything....

But can't figure out what is causing it not to work when hooked up the correct way --- they have changed out relay switch, new low pressure switch... but don't know what else they can do

We do have it scheduled to take to the local deal on Monday

not hard wire to the compressor- meant direct wire (told you I dont know anything about cars!)
