My Hummer H2 (2007) driver seat heat comes on and off

Customer Question
My Hummer H2 (2007)...

My Hummer H2 (2007) driver seat heat comes on and off randomly. The indicator lights do not come on anymore and the backlit switches do not light up anymore. When it does turn off it is only for 5 minutes or so.Is this a reprogram the module thing or replace the door control module?

Mechanic's Assistant: Do you have the trouble code? Do you have a code reader or scan tool?

No DTC's but I did not scan.

Mechanic's Assistant: I'll pass this info along to the Chevy Mechanic so that he can get you a quick fix. Are you fixing your H2 yourself? What have you tried so far?

Thank you. Yes I am doing it. I just unplugged the heater on the seat and have done some research. I still have to check the inputs to the switch from the ddcm.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

That should be good.
