The4 first thing to do is test for power and ground at the motor itself and determine which one is mission if any and we take it from there.

That tends to point to a bad blower speed resister but a bad motor could be what took it out too.

Thanks for your help. How to check the resister? Or do I just need to buy a new one? Also how to check if the motor is bad and won't mess up the new speed resister?
