Default Re: Wolfman's Guide for Diagnosing the Radiator Cooling Fan

Don't overlook the possibility of a bad ground for the fan motor. One side of the fan motor plug should be +12V with AC on or at 'hot' temperature (decided by PCM via ECTS I guess) and the other should be grounded. For me, for some reason there was no path to ground. I ran a jumper wire (make sure you use similar size wire to what's on there...) to the body and it fixed my problem.

REWARD EXCELLENCE!
