Mr. Dalton,
I'll probably have to test tomorrow since I already spent 3:30 hrs this morning and I have to work to make money. Meanwhile someone suggested to check blower motor relay. I've been looking at Mitchell repair manual on CD, and I don't see that relay. Is it same as "Electric Blower Control (Rear of engine compartment)"? If so, what does it look like? And, yellow, is this one of wires for the blower motor regulator? I'm just curious, how could this regulator go wrong when there are no moving parts? It looks like a few wires are soldered on to the aluminum plate. The only thing I can think is that the wire must be cut somewhere along the way or came apart at soldered point.
