No Heat

The temp is below 0 and I have no heater fan. I have looked at the fuses. What's there look ok, but some are missing. And I can't find my books on this thing. Does anyone have a diagram? And or suggestions?

Thanks

Hi!
Temp here dropped to -48 on Monday (with windchill factor) Damn cold even for here! Lack of heats a drag.
There are 2 things to check. First, turn on the fan and smack it a bit.
Many times with old heater motors this will restart it.
Also, get a test light and see if you have power here while you're at.
The '77 to '90 models had the easiest fan to reach, btw!
Second, the fan switch & connector itself are known to get fried over the years. This would involve removing the heater control / radio unit to check/replace.
Hope this helps....

Thanks Jim,

yea, it got down to -34 without the windchill factor here in Mt. .

This thing has been driving me nuts and I don't have a wiring diagram to help. Which wire at the blower should have power to it. and which wire at the heater switch should have power. If I knew those answers, I might have a chance to bypass a switch problem.

Just a quick note. Seems that one of the missing fuses was the culprit. Sure would be nice if the slots were labeled better. Anyhow, I don't know which of my kids pulled the fuse or even why. But, it's working for now. We'll see if it blows or what.

Thanks,
