I have been trying all day today to get my heater blower to work and am having no luck. The heater lever on the center console has never been hooked up since I have owned the car, so that was my first step, locating and hooking up the correct wire to the lever. Once that was done I made sure that I had a good working relay in the correct spot on the relay board and I gave the lever a pull. All that I hear is a click telling me that the relay is working, but no fan. I have run a hot wire to the fan and know that it works. I have tried two different relay boards and nothing changes. I am sort of out of ideas and am now coming to the experts. Any ideas?
I took my fan motor out and opened it up. Inside the motor a piece of wire wrapped around an insulator had broken off. I re-soldered it and it worked.
check inside the white connector where the fan plugs in...
that is why mine didnt work.
it looked like it was plugged in.
pull on the wires slightly if they are loose it will come out...
then plug it back in.
Check for power on the relay board. Some year models used a jumper on the 12 pin plug at the relay board to take the power from pin 11 to pin 10. It's the green wire in this pic. Also the tunnel switch/lever needs to ground when in the full on position.
No sorry my fan didn't work at all. I directly wired it to the battery before I did that to isolate my problem.
Check the fuse 25 Amp. I would guess thats it open or the contacts are bad
If the fuel pump is stock and runnng then it is not likely the fuse. Only takes a moment to check it though. Since the blower works when hot wired best bet is to follow the harness back with a volt meter. Delivery end of the cable then pin 11 of the 14 pin connector and then pins 10/11 of the 12 pin connector.
remember to protect your points when doing extensive trouble shooting with the ignition on - remove the hot wire from the coil.
Excellent!
Very helpfull, I think I have the same problem. I will check that ! ...
