The blower only working on High is a very good indicator that the Blower Motor Resistor has failed.

1992 gmc pickup keeps blowing heater fuses I replaced the blow motor and it keeps blowing


Have you replaced the blower resistor . some times they can cause the fuse to blow . You may need a muiltmeter to test the current draw on the blower motor circuit. the draw should be less then half of the rated fuse .( 20 amp fues draw is less then 10 amps) You did not say but does the blower work on high only or the lower speeds with out blowing the fuse ? if it does work on low or high with out blowing the fuse i would replace the blower resistor

Gmc 2006 Sierra fan switch was not working on all settings now after being set on high it would not shut off then it stopped but smoke began coming out from under the passenger side dash


There is a resistor board in there that controls the voltage to the blower fan. When the resistor dies the fan only runs on high. The bad part is it overheats the wires and starts burning things. You will probably need a socket and pigtail too. Both available from the dealer. Usually not very expensive and you can do it yourself.

05 GMC sierra heater blower stopped working. It used to work on setting 1-4 but lost 4 a couple weeks ago and now none of them work. Is this a bad blower , resistor or both?


The resistor is most likely bad but should still work on the highest setting.Would check pigtails to the resistor and to the blower motor for burnt or discolored wiring.You can try tapping the blower motor and wiggling the wiring harness too see if it will work on the highest setting. It is possible that the blower motor is bad as well typically when you lose the speed selection it is the resistor but you should always have high speed.
