Default Condensor fan not working,HELP!

My A/C condensor fan is not working (85 Coupe). Does anyone know where to start the search for what is wrong?

Thanks in advance,

What is a condenser fan? The A/C fan under the dash would be for the evaporator. The fan closest to the condenser is the engine axillary cooling fan, if your car is is equipped.

?????Which?????

Assuming it might be the engine auxillary cooling fan, what have you done to determine that it doesn't work?

Yes it's the Aux cooling fan. It does not run even when the car is sitting still (HOT) with the A/C on.

How hot is hot? My 1984 Factory Service Manual doesn't show the specs for the fan operation or the wiring schematic for your 1985, but your's should. The fan MAY not be supposed to come on until about 235*. I don't know if the aux fan is triggered on an '85 by the A/C or not. Your manual will tell you. The first, and simplest test is to remove the wire from the auxiliary fan temperature switch and ground it. If that runs the fan, then you know that the fan motor and relay are operational.

RACE ON!!!
