Heater/ A/C Blower motor
My heater will not blow any air out of the vents with the switch in any position. I have checked all the wires and get aprox 5v 9v 12v through the switch. The ground is good and I even cleaned the switch. Does the A/C use the same blower as the heater? My A/C blows air just fine.

The resistor dries out and goes bad, but it's an easy fix. You'll have to cut the squirrel cage (fan cover) sealant to get the cover off. Also, the fan switch fails, too. You'll still get good voltage and ground, but the switch won't close the circuit for you.

Looks to me like its probably the resistor, Now how do I go about fixing it?
Edit: Its the switch, jumped the pins and fan runs at all 3 speeds.
