My A/C blower motor stopped working
My A/C blower motor stopped working. I removed it and checked voltage at the plug, 12.4vdc. When I plug it back in, it starts momentarily, but stops. It’s a nonreturnable part based on its electrical nature, so I want to be sure this is the problem.
Use a different source of power when testing the blower motor. I use a Power Probe when doing this in the shop. It allows you to apply power at a push if a button. If you do not have one you can use jumper wires from the battery also. If you find your blower motor is functioning just fine with a separate power source, check your blower motor resistor next.
