High Speed Heater Blower Not Working

[doninkalamazoo]

The high speed heater blower setting on my 2002 Envoy stopped working. Is this a simple fix, or will this require a trip to the dealer? Speeds 1-4 work fine speed 5 does not. Thanks!

Ended up taking it to the dealer. Bad blower resistor, $220.00 fix. Replaced the same resistor on my 1998 Malibu.

I have the same problem with my 2003 envoy xl. All the speeds work properly except for high. I was told that this is the resistor. Can someone clarifiy this as I will fix it myself

I am hoping that the dealership didn't soak you for this part or labor. Can someone shed some light on this.

Yes, it is the resistor. It is usually mounted on the blower motor housing and actually is set inside the housing, I guess to keep it cool from overheating?? When I replaced the one on my Malibu, it was simply held on by two screws. I had to remove some of the paneling under the glove box too. As stated earlier in my post, the Dealer charged me around $225. Good luck!

Gentlemen this is a 2 year old thread please look at that before posting, BTW the resistor is not inside the case it is on the outside housing. Thanks, this thread is closed.
