Can someone please tell me the operation of the condenser fan. The fan works if the car over heated but doesn't come on when the a/c is cut on, I was wondering what tells the fan to cut on, I have switch out relays but it still doesn't work. Thank You

My first try would be you have a bad relay. There are 3 relays located on the passenger side of the blower/duct assy inside the pass footwell. The one with the Purple, Silver w/Purple Stripe, Silver w/Black Strip, Brown w/White stripe is the guilty culprit. Just replaced mine. The only other culprit is the Trinary Pressure switch. That's a spendy part, plus evac and recharge if that's the issue.

Cheers
