well I Had a turn for the worst - lol while messing with the buttons I was rolling down the passenger side window and the regulator broke... one side is still on and I was able to power it up while holding onto the glass... but I pulled it apart and only the back side moves up and down... the front is trashed. So now I have a goofy seat heater to fix and a power window regulator to fix..

not cool

Since it is starting to get a little chilly here is Ohio I decided to repair the heated front seats in my 2003 H2. When the heated seat buttons were pressed on either door they would light up for half a second and then go out. No heat to either front seat. I figured I had a short in one or more of the seat heater elements which I confirmed to be driver's lower heater element only. Problem is the 2003 H2 made the seat heater elements as part of the leather seat cover. $$$ to replace. So I bought a seat heater element for a full size Chevy truck of the same year (GM part number 88940288) and installed it between the foam and the seat cover. Now both heated seats work fine and you don't notice the slight extra thickness in the driver's lower seat.




I noticed this today... anyone else try this? I wish I could get a used one and plug it in to test...

 

That sounds like EXACTLY what I need to try!!!

 

 

 

That's really good news and good to know. I still haven't had time to look into my problem. It is next on my list. I will report back as well once I dig into it. My front seats look brand new, which is unusual for decade old leather. I have a sneaking suspicion the previous owner replaced the seat covers and did not swap over the heating elements. I won't know until I look though, hopefully this weekend.

 

 

I finally had time to look under my seat, on the drivers side nothing is plugged into the green connector. So looks like my theory was correct, the previous owner replaced the seat bottom but didn't move the element over (lazy b@stard). I ordered the heating element from The Seat Shop for GM part equivalent 88940288. I didn't get the GM one because it was $150, and I didn't get the Dorman one because I've read the connector wiring isn't long enough to reach under the seat. Hopefully The Seat Shop one is good ($70). I'll report back after I test/install it. It says it's made for Cadillac and others but I think it'll work for the H2. I know that if one element is jacked up then by design none will work. So I'm praying after I replace the drivers side seat bottom element, then the drivers side back and passengers side back and bottom will start working without being replaced.

 

 

I plugged in the new heating element and all my heated seats work again now. Luckily for me, it was just the seat bottom leather being replaced and element not transferred, and not the back shorting out, the back seems like a bigger pain to replace. I will take pictures when I remove the seat cover and install the pad.
Pad I got off Amazon that worked on my 04 H2:
