I installed new resistor and connector and speed 5 won't work on blower on 2005 gmc sierra


High speed on the blower fan does not work thru the resistor.
There is a seperate circuit that sould feed 12 volts directly to the motor. If you have access to a schematic it would help.
The connectors for the high speed, burn out a lot. If you cant find I could look it up.

2003 envoy heater blower does mot work on any speed


The switch on the dash could be defective or look for a module near the heater fan on the fire wall side of the engine dept. Trace the wire attached to the fan motor back to help find the module, check it with your nose to see if it smells burned. You will not mistaken the smell of burned electrical components.

Hello: Under the passenger side of the dash on the bottom of the heater case you will see the blower motor and the blower motor module, check the six wire connector and see if there are any burned wires, if there are Chevy/Gm have a harness you can buy and replace the burned part. Also the module may be burned, if so replace it to. Hope this will help you.

My 2006 gmc sierra defrost blower doesn't work I checked the fuses any ideas


Make sure you check fuses with a test light or ohmmeter, because just looking at them is not good enough sometimes.
Have you tried high speed, because the lower speeds use resistor packs that can burn out. They are between the switch and motor, usually in the air box. While there, you will be able to see if the switch is bad, if a test light shows anything. If there is power right at the fan motor, and ground, and it still does not work, it has to be the motor itself. But hope not, because hard to get to.

2004 GMC Sierra 4dr truck. the fan does not work


The switch or the wire harness at the blower motor has gone bad. The highest setting 5 has no resistor, so the blower runs on high but the high current flow ends up burning up the switch's contact on that setting or the resistor wire harness at the blower motor has gone bad. Common would be the switch it self, if the switch is good. Then it's going to be the wire leads at the speed resistor by the blower motor under the glove box by the passenger leg compartment. Keep me posted, be glad to help you get your Sierra running 100% again soon.

MY HVAC fan stopped blowing. Checked all the


Check the blower motor speed control resistor pack is ok.
(The resistor pack is usually located in the blower fan ducting in the air flow).
Check condition of electrical connection terminals on the blower motor circuit - these terminals pass considerable current and over time may fatigue overheat and loosen.
Check operation/replace any blower motor control relay,
Check the blower motor will run if +12v directly applied to the blower motor.
Check operation of the blower motor speed control switch is ok.

Heater not working


The problem is probably the blower motor resistor. I'm not sure where yours is located exactly. They can be on the firewall under the hood or some are near the blower motor under the dash.

1998 GMC Sierra pickup truck cabin fan problem


Your blower moter is under your glovebox and very easy to replace.I dont think thats your ploblem.I would pull off the dash.It will snap right off without breaking anything.Then pull out the part that holds the selector switch for the fan speed.Then you unplug that switch.Clean the copper contacts.Plug it back in.If everything works again like it should and did in my truck then it is either that switch that is bad or the wiring harness.I would replace that switch.
