1993 Toyota Camry 1993 toy camry no power to ac clutch

Hi davidocon,

Is there power supply to AC clutch relay?
Is the relay clicking when the AC is turned on?

yes there is power to ac cluch relay,I also replaced the relay.checked relay for power and good ground,no problem found,I checked the ac control switch on the control panel ,ok,replaced the swich because I did not hear the relay clicking.still no powert to ac clutch.

Hi davidocon,

The AC clutch is a special type relay, did you replace with correct type?

There are 4 points but only 3 are used. Check the Blue/White wire from realy to see if it is grounded when AC is turned on.

Does applying ground to this wire operate the clutch?
