Fan problem

I have a 1992 SC. My fan won't kick in. I hot wired it and it works. I checked the relay and it's ok. The book indicates it's a bad PCM ... does anyone have any othe ideas or know where I can get a good used PCM?

first, see if it works when the A/C is on

If it is the PCM try 6thplanetusedparts.com.

Have you checked the temp. sending unit for the PCM If it hasn't been change it may be cracked and shorted out & not sending any data to the PCM so the PCM thinks it cold. This is only about a 15 buck part and change in 5 mins. without draining no collant. Good Luck. :2cents:

on my 96 i ran a hot wire to a switch and then to the fan w/ a ground goin to the fan ground to.... disconected the factory plug, now i can turn my fan on when ever to keep the motor cooler ....ALSO TURN IT ON WHEN YOUR A/C IS ON
