Default Re: Heated seats turning on by themselves

Hmmm... Today the plot thickened. Sometimes, but not always, the aberrant heated seat behavior ceases completely if I turn off the heater.

In addition, I found "Technical Service Bulletin #01850" addressing this behavior at a site for Chevy Silverados, which I've heard share many parts with the H2.

Anyone know what I can do about the bulletin?

Thanks,

Ken

Your BCM might need to be reprogrammed. My truck had the same problem and they told me that they might just have to reprogram it for me. Dropping it off tomorrow to get it checked out.

I had to have the computer reprogrammed on my '05 to fix sporatic seat heater issues. The buttons were not working correctly or at all sometimes. The dealer reprogrammed and they've worked ever since.

havent had the trouble on the H2, but i did have the problem on my 03 and 04 avalanches, seemed like the problem just went away...who knows why it started or why it stopped. kinda sucked in the summer getting a hot ass when its 90 degrees out.
