How do I fix heated seats?

[Hummdinger03]

Just purchased an '03. Same seat problem as you guys above. Push the front heated seats button and the light flashes once. Can hear the relay below. Rear seats work fine.

If you guys have found any fixes, I would greatly appreciate your update.

Cheers, J

Update: Have taken the H2 into the shop. Turns out the problem is the actual heating element under the seat. All other systems/relays work.

New problem: GM parts department has informed me that the heated seats element for the H2 has been discontinued, and there are none available.

Any advice on hunting down a replacement element aftermarket? Haven't seen any on the internet. Does anyone know if I can use the element from a different vehicle?

Thank you,

J

Not sure but maybe the heating element for a Escalade (Tahoe, Yukon) will work. I was amazed at how many shared parts the Escalade has with the Hummer.

The Result:

Wanted to post a follow-up in case anyone came across the same issue.

Had a mechanic look at the seats, followed the electrical trail, problem was the seat heating element. Due to use/wear, the elements had fried. With one seat not working, it prevents both front seats from working.

Stupid GM design: the heating element is integral to the leather seat. Can't buy a replacement element alone. A new leather seat cover is $600 from GM, and that's if you can find one (no longer produced).

I was able to find a scrap hummer with matching leather. Swapped the seat leathers = warm bum!

Cheers, J.

Hi, what do you mean seat leather? the whole seat ? or just the leather covers?

I have the exact same problem, 2 front seat, lights come on and goes off insatntly or after few seconds. Dealer said costs $7,000 to replace, I finally agreed but dealer later said no more parts available. Same story as above, one is broken, caused both to stopped working, back seats ok. I had the same original 2003 H2 since Oct 2002. Seat warmers worked fine for few years. All else work perfectly for almost 10 years 140,000 miles.

Seat leather= the leather that wraps the foam on the seat.

As I mentioned in my previous post, the heating element is integral (part of) the leather.

Good luck.

There is nothing magical about a heating element. I'm sure its sewen/glued/taped into the seat. I'd google aftermarket heated seat element. You just need the wire. May have to modify/eliminate the factory plug for what ever comes in the element.
