My blower motor has been working only on the highest setting for a while now. Finally getting around to replacing it. It was not an easy job for me, my hands just dont have the dexterity they used to after surgery on both hands. I have almost everything back in except for the top screw on the resistor (not sure how I'm going to get that screw started). Before more wiggling and cussing I decided to check the blower at this point. It works on settings 3 and 4 but not 1 or 2. Any ideas? Bad new resistor? Is there a way to check them? The old one does not show any signs of overheating or melting.
