Blower motor not working. I replaced the resister and checked motor. Pulled it out put voltage on it and it works.I also has voltage at motor and fuses are ok. What could I be missing. Thanks

What about the connector on the resistor? Is it corroded or burned up?

Have you checked for a bad ground? If you have power to the motor, it should run.

If you have power at the motor, the ground is supplied by the switch, through the blower resister. I would do some testing at the resister with a test light that reads a ground signal and make sure you are getting one from the switch that moves to different wires at different speed settings.

Wrench, I believe you got this one wired to the T-I did one last year same vehicle as my cousin the culprit was the resistor-not my suspicion on the blower switch

Yes Ras, My suspicion would be the resister too but the switch is a player and can't be ignored.

Both of these guys are correct. The ground is through the switch. If there is power to the motor, it has to be a ground issue. Since the resister is new, chances are it is good. Think about it. When you check for power, you are most likely using a test light or volt meter. Where is your ground? It is one you supplied, so the power can complete the circuit and show power. Once you remove your ground, the power is still there but has no where to go.
