My blower fan only works on high

In my 2000 GMC Sierra the blower fan only works on high - the other speeds (1-4) do nothing. Is it a bad resister? the fan sounds fine

    Hi Skip!

    I have a 99 Safari with the same problem. I can get a resister but don't know where to go to replace it. Can you give a little more details on how to access it?

    Thank you!

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.

I Have an 03 gmc sierra 2500hd. the problem is the manual speed control knob for the heat/ac only work at the highiest setting. all of the lower speed controls don't work. What do you think is the problem?


there is a resister near the blower motor that controls the fan speeds that is most likely your problem when it goes bad the blower motor will only work on high i have changed many of them on many cars & trucks

2005 gmc sierra heater fan quit working. I lost the fifth speed months ago and a couple of days ago lost the other four, the first day the fan would come on sometimes while driving then quit after a while...


1-4 speed are the blower motor resister . It controls all 1-4 speeds, also it's under the passanger side dash around fan, the 5th speed runs off a fuse the is located in the fuse box. It's one of those square fuses , not the relays but fuses. The resister will run $15 and fuse $5 . Good luck. I have replace these before

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.

Heater fan blows in position 3,4,5 but not 1 or 2


the blower motor resistor is fried...it is located under the dash, passenger side, costs about 10 bucks and takes 5 mins to install...happened to me, it needs to "resist" or limit the power for lower speeds, that's why it works in 3-5, no resisting needed.

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.

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.
