Well if it does have one it should be by the blower motor or behind glovebox but my best bet its ure thermistor its bad, assuming fuse and relays are fine, remotely think ure controls are bad.

SOURCE: switch for blower motor for heat & ac

Sounds like you need a blower motor resistor. It has bad paths between the 1 and 2 speed circuits.

SOURCE: gmc sierra blower switch

last place to look is the resistor block located in the duct work for the blower (fan). it should have a wiring plug going to it and be held in by a couple screws. look on the passenger side near the fan itself.

SOURCE: need to know where the heater blower motor

Unless they moved it and are still using the same part,I would say that this one is located behind the glove box sandwitched between the underside of the dash and the top of the airbox.The blower motor is mounted to the underside of the airbox.

The blower motor is on the passengers side under the dash.You might have to remove the a lower panel.This is the insulator panel.If the blower works at all just turn it on and follow the noise.Hope this helps.Good luck.

Service 4 wheel drive message comes on and no lights for 2and 4 wheel drive come on. On my 2004 gmc


Often lights under a dash or indicators just blow out bulbs. If more than one thing isn't lighting and are centralized check fuses to see if its blown. Bulb or fuse. IMHO. MIGHT be a sensor on tranny too. Hope not.

Here's a video with detaile dinstrauctions and other people's fuse questions. New fuses?

1991 gmc sierra 1500 p/u-can not locate blower motor speed control resistor. I've looked under dash, pulled out glove compartment, looked on firewall, I give up.


If its not near the blower motor, it may be on the hvac box on the firewall in the engine compartment. It depends on if it has ac or not.
They are usually behind the glove box mounted in the side of the heater box.

1999 gmc sierra 2500 6 liter ran out of gas now won't start


If you are at or near the 100,000 mile mark then your fuel pump may have failed. If you remove the fuel filler cap and listen carefully at the filler neck while someone turns the ignition key to "run" [don't actually crank the engine] you should be able to hear the fuel pump buzz for about a second and a half as the key is turned On. If you don't hear the pump buzz then odds are your pump is dead. Your pump may have actually failed making it appear as though you ran out of fuel. Not to uncommon. Hope this helps and good luck!
