blower motor resistor

grande_guerre · Apr 19, 2006

my blower motor hasnt been working for awhile, and looked at the resistor. is it supposed to be missing the pin in the upper corner??? if not, i'm pretty sure the problems in my switch, i think the wire is all corroded. maybe....

look at wiring diagram here:

--OR--

Jumper-wire neg. & pos. to the blower...if it spins, it's good..?

I would then assume the prob. is in the wire, or switch.

ya, the motor works fine, its in the resistor, wiring or switches. but i'm still curious if the resistor is supposed to be missing the one pin....

another question: i measured the voltage out from the motor. has 5 volts on low and high, and about 7.5 v on m1 and m2. if the thermal limiter opened, would it cause this???

Here is some additional information to help you troubleshoot the problem. When you say, "out from the motor", at what point are you measuring the voltage? These diagrams are from the 1983 EVTM but that circuit hasn't changed, so it should also be the same on your truck.

Good luck,
