Question about 2004 GMC Envoy
My 2004 gmc envoy seat heaters do not work. There is no power to the switches as neither driver or passenger lights come on when buttons are pushed. What could the problem be. I could not identify the fuse that controls this in order to check to see if it is blown.
You may want to look for the fuse in the fuse panel under the back passenger seat. Also, it may not be a fuse, it may be a relay. I had the relay that controls the movement of my seay go bad and when i took it out it was extremely hot and burned my fingers. If it is a relay, I would suggest using a pair of pliers to pull the relay out. Hope this helps!

I have the same problem with my 2004 HD Sierra. I found that the "MBEC" 50 amp fuse in the under hood fuse box had blown. Replaced that and it works now. This has happened twice in 2 years.
