My sons 1991 C1500 2WD blower motor only works on High position, I have yet to find the problem:

Changed Resistor and Heater/AC Control; still not fixed.

I will try and locate the ground wire for blower and check that.

Keep up the posts; I have been working this issue on and off for over a year!
