zdriver123 Posted October 16, 2010 Share Posted October 16, 2010 I went out to my 85 GL wagon and The heater fan did'nt turn on . I replaced the fan itself, the switch, and the blower motor resistor. neither fix got the fan working. I have power at the two fuses marked for heater. I was wondering if anyone had the wiring diageam so I can look to see if tere is anything else in the circut. Anything would be better than what I have. Thanks in advance.

Cougar Posted October 17, 2010 Share Posted October 17, 2010 There is one more piece of the puzzle missing and I suspect it is the trouble. It is the blower relay. It is under the dash near the steering column area I think but I'm not sure. Later versions have 4 relays in a row and the blower relay is one of the 4. Your model may be the same. If you don't have a test light probe to check for power with you should get one. It will help you see where power is getting to and save you time on repairs like this.
