help with heater problems please
I don't have any power going to the blower motor. I have ground but no power. I don't think its the resistor because it doesn't work on high either. In my experience the high setting always gets power straight the battery correct? I checked the fuses under the driver side dash and they all checked out ok. Is there any fuses anywhere else other than the one under the hood?

Could be in the climate control panel. Also, if you directly wire the hot side of the blower wire to the battery, does the blower run?
If not, then suspect blower motor.

There isn't any power at the harness that plugs into the the blower. I'm planning on testing the swithc tonight. So are those the only fuses or have I over looked some?

Don't believe there is a relay, but I think there could be a fuse for the blower motor circuit both in the kick panel AND in the power distribution center; that's the way I remember it on my 99.
And if fuses check out, the switch itself is certainly primary suspect. See if you have power before the switch.

My 91 had a fuse under the drivers side kick panel area for the blower motor. Also if your thinking it's the switch they do like melting behind the dash for some reason

Thanks guys. Its not my main veheicle so I haven't been in a big hurry of fixing it. I work 60 hours a week so its hard telling when ill have a chance to pull the switch out but ill post the answer when I get it fixed!

There isn't power at the switch either. All the fuses are good at the box under the hood as well. Does anybody have a wiring diagram that could tell me which wire is the hot wire going to the switch? If so ill just splice a new wire in to it. Any other ideas?
