My 2005 Chevy Colorado's heater/ AC blower motor control knob only works only on high (No.4 knob position) This part was repaired by the Chevy dealer once and it worked for about 2 weeks then it was down again. I have replaced the blower motor resistor after that and worked for about a week and it went out again. I'm baffled!

    So what do I do now? (too much draw from the blower motor) why does other truck exactly the same as mine have no other problem once the resistor is replaced?

    Same thing happened to me. Dealer replaced a burned out resistor on the switch and no problems since then...

    It is not the resistor but loose wiring. I have two Colorados and both have this problem. If blower doesn't work you can just move the wiring underneath the glove compartment and the blower starts working at the other speeds. You probably move the wiring when you change resistors and it works until it looses connection again. I have not taken time to pinpoint the source yet.

    i had this problem a while back, took the plug out from under the passenger side dash (under the glove box) got a wire brush and some electical cleaning spray, lightly brushed and cleaned the contacts for the selector switch and haven't had a problem since (problem was about 4 years ago)

    i had the same problem so i took it back in and it is a resitor that keeps going out they had problems with them for awhile and some resitors are made different and some are just out right bad

    Replace the pigtail connector when replacing the resistor. Once the wire connections heat up they are loose and will keep heating up burning out the new resistor.
