1990 Pathfinder se v6. Fan blower or ac compressor wont' go. I have pulled the fan, works fine on the bench. Pulled the ac switch, seems ok, voltage at the terminals. Where is the actual relay for the fan/ac system. The schematics shows it, but there isn't one labeled as such, thanks in advance for advice on this.

 

The AC relay is located on the RH fender apron. The blower motor relay is located right beside it.

 

David, I have a '97 Pathfinder with a resistor problem and my fan has defaulted to the high setting. If your '90 is not too different I can give you 3 places to look. 1 - The fuse, 2 - the relay block which on mine is blue and at the top of the fuse box assy and is about 1.5"x1.5", and 3 - the resistor assy which is located behind the glove box (the coupler from the blower plugs in here)
