The fan has a thermal switch in series with it. Find the thermal switch. Make sure there is electricity to the switch, and make sure the fan comes on when the switch is bypassed with a wire. It's either the wiring, the switch, or the motor. If the motor cannot be turned by hand, that's a strong indication of a motor issue.  Signature"C'est un Nagra. C'est suisse, et tres, tres precis." Thankyou for that i know the basics,but anthing more than that im stumped. >>Hi im new to this,can anybody help me with this problem??.I have a L reg >>cavalier,it drives fine but the fan just wont cut in,and when in traffic temp [quoted text clipped - 7 lines] >It's either the wiring, the switch, or the motor.

Well, what voltage are you seeing on the motor with a meter? Have you traced the wire from the motor back to the switch yet? --scott Signature"C'est un Nagra. C'est suisse, et tres, tres precis."

So take a tail light out and get a piece of wire and bridge it across the motor terminals. Does it light up? --scott Signature"C'est un Nagra. C'est suisse, et tres, tres precis." |
