Mike1995, after I put the new resistor in and the motor still didn't work I disconnected the motor and checked the DC voltage that would feed the motor (I just checked voltage between the two wires feeding the motor). I had 0v no matter what fan speed I tried to run at. To be sure the motor was good, while I had it out of the car, I hooked it up to a 12v battery and it did run, so assumed the motor was good.
75 racer, I'm not sure if I can manually start it, but here is what I've expereinced since I've owned the vehicle before the blower stopped working...If I turned the heat or A/C, the blower would start blowing, and the automatic temperatue control would only control the amount of hot or cold air that the blower was blowing, but the blower always ran at whatever speed I set it at (the ATC didn't seem to control this). I hope that is clear enough. Thanks for the tip, I will see if I can find a place that has a scanner. If I remember right, AutoZone does that for free, right?
