1997 defender nas. condesor fan inop

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

Here's a snap of the wiring diagram for the A/C circuits. Hope it helps.
