heater motor question?
Hi y'all,
I have a 2001 gmc sonoma and the heater recently stopped blowing out heat. All 4 of the speed settings don't work. They were working fine one day and then the next time I turned my truck on they wouldn't work. Does anyone know if this is from the heater motor going bad, or just a resistor or something?
Thanks a bunch

Welcome to the site!
Unless there's something unique about a 2001 Sonoma, there's no such thing as a heater motor. Its just a fan, which blows either cold or hot air out the vents. Sounds like your fan just took a poop.
Could also just be a fuse that popped, so check it.

This is for both the 2.2 and the 4.3 engines, same blower motor. $91.00 Usually this place has great prices.

Thanks!! I looked further into that blower fan you were talking about....I also came across a blower resistor?? Could that be my problem, or do you think it is just the blower fan because it doesn't run?

hey, thanks for the replies
I checked my HVAC fuses and they looked good. I decided to then see even if the AC worked in it and when I switched it over to AC the fan came on!!! But there seems to be another problem.....I have fan settings 1 - 4 and 4 is now off, but is supposed to be high. Anyone have an idea why the settings would mix up?
Thanks again

Sounds like a problem with the selector itself. Its strange that it will blow with the A/C on but NOT with the heat on. With the Trans Ams and Camaros the only difference between A/C and Heat is turning the "cold/hot" **** from the cold side to the hot side or anywhere inbetween to regulate how you want the temp of the air coming out. You leave it on "max A/C" even when you want heat. You could also move the selector off of "max A/C" and just select the different vent selections and the compressor will turn off. But the fan is just a fan, it doesn't know cold and hot. By leaving it on "max A/C" when you want heat you will still have the system dry the air before it comes out of the vents.
Maybe the Sonoma is different.
