To keep my truck from low idle I would press ac and run the fan which opens a solenoid to let more air in the plenum increasing rpm.
Two weeks ago the blower motor stopped working. I ordered a new one on Ebay for 30 including shipping
Installed the new and it ran several times that afternoon making a hitting noise sometimes. The noise would go away. I wondered if I did not have it aligned correctly and screws not tight enough. Total time running 3 minutes intermittantly. 0 volts when fan set to off.
Then the motor stopped completely. I do not know if I put stress on the fragile taped power and ground wires and caused a bad connection.
I placed a voltmeter from Habor Freight on the power wire and ground seeing 1.2 volts whether the fan setting was on setting 1, 2, 3 or 4 the fan speed.
I dropped the motor back down. Trying to figure out what to do next.
