Anyone know if this is specific to the H2 or if there's an equivalent part number for other gm trucks? I'm having a hard time finding the answer researching myself. See attached photo. When I try to use my heated seats the button keeps going crazy like a ghost is continuously pushing it over and over. I'm pretty sure it's not the heating elements becuz I recently replaced them, and when that was the problem the switch was immediately cutting off and not cycling through randomly.

 

nice

 

sorry, my phone was being dumb, I edited the post now

 

i have seen them in other gm trucks but sometimes they have pedal position buttons as well integrated. you can pop them off and try clean the green crusties from inside i did it to mine before i realized it is my heater element thats bad. they can get wet from the water leaking in by the A-Pillar / roof body seal same goes for the windows / mirror switch. if i remember the clip is on the back and a hook on the front. you try push the switch forward to release sometimes you need something flat to push the rear spring clip in while lifting the back a bit

 

I'll try taking it out and cleaning it. What were your symptoms for the element though? Was it going from level 1-3 randomly? Or was it shutting off completely when you pressed it on ?

 

it turns on a few seconds and turns off.
once in a while it works but only worked properly the day i purchased the truck. by the next time i tested it it did not work any more lol. i bough the truck as is so could not take it back.
but your issue sounds like you might have dirty or corroded switches.

 

If you want to replace it there are plenty of them used on eBay but as Bronx mentioned, many do have the power adjustable pedals buttons as well.

Like that one - it will still work perfectly fine. Here is another interesting tidbit. If you get that one you could replace the DDM (drivers door module / power window switches) specifically from a 2005/2007 H2 and those pedal buttons would function as "global windows" buttons which came on the 05-07 H2's. I actually added that to mine. The 03/04 H2's did not have that feature. I made a thread about it some time back when I did it. https://www.hummerforums.com/forum/h...-2004-a-38594/

The global windows is a pretty neat feature. One quick press of either button opens or closes all windows at once....

 

Update:
I did absolutely nothing and it seems to be working fine the last few days. If it happens again I guess I'll take it out and clean the electronics on the button module.

 

I always thought the global windows button was awesome. That's some really good info. Mine is an 04 and I don't have it. Thanks!

 

I have it now on my 03 but it is not a cheap upgrade since the DDM is so expensive..... I'm not sure if a DDM from an GM SUV with the power adjustable pedals would work but I suspect not. The programming is likely specific to the H2 (it is the only GM SUV with the global windows feature) to control the windows. Using a GM Tech2 it even sees the buttons as power pedals. I guess GM did not bother changing what it is called in the Tech2 software. If you get the buttons and the DDM it is 100% plug and play and literally a 10 minute upgrade though.
