Do they turn off randomly while in use, or intermitantly not work. IIRC, if the seat belt is not connected, the seat heaters will not operate on that year.

They just come on while I'm driving with the seat belt on.
You can see the lights on the heat switch go on for about 30 seconds and then go off on their own. It does this over and over.
Is there a sensor in the door I can replace??

Default 03 heated seat issues

I also have experienced the driver seat heater going on and off, and clicking under the seat. Is there a way to check if sensors are bad?

Angry 2004 Suburban w/ Seat Heater problems

I have the same problem, although it usually just turns off after 45 seconds. The dealer wants $900.00 to fix the problem and says the capacitor is failing? WTF?? There has to be a cheaper fix. My fuses look good, but something is tripping the heater. I live in Houston and only use the heaters about 2 months out of the year. Any help is appreciated.

In addition to the above, my passenger side window will no longer operate. Could this be a driver door module?
