New "How to fix the seat heater" thread.

Thanks!

Is there a procedure for replacing the back heater?

I was surprised that when I finally removed the bottom portion of the seat (following all the steps in this thread), and there was no connection to the seat back. How is the seat back heater connected to the seat cushion heater?

I just did a search for the Dorman 641-106 on Amazon, and they say it does not fit my 2003 Envoy SLT.

for starters , amazon sucks as a reference for car parts

if you are adept enough to tear into a seat repair--- surely you can see the electrical connection for the BACK heater pad- LOOK FOR IT

Then go to dormanproducts.com and look at the pic for that part number.

( yes, i know it doesnt list it for your 03 envoy-- but i'll just bet its the one you need)

OR

if you prefer the DEALER ROUTE, here is your officail GM part number

Thanks ce8204.

I realized after submitting that post that there must of course have been a connector for the back of the seat controls, I just didn't notice any plug coming out of the bottom of the back part of the seat.

What's weird is that the Dorman part # for the cushion part (described in this thread) has instructions showing that the heating element is for the cushion AND the back. That's one reason I don't trust these Chinese/Taiwanese instructions. Delco isn't any better, all their parts are sourced from overseas now, so they don't have any better quality than the cheap Taiwanese junk.

I need to do this on both front seats in my Wife's 9-7x will the Dorman 641-107 part number work? It seems like it should work in all the GMT360 platform models. Hers is an '08 model.

[ce8204]

yes it will work just fine

Thanks, I thought so but wanted to be sure before I ordered two of them.
