Temp control sensor, sounds like, Check the sensor and see if its wide open, it should shut the curcuit once its heated.


Good way to test is set the OHM metre resistance, Shouldnt have a reading when its cold and if does move than its stuck open and should be replaced, And if has no resistance and shuts off when heat applied to it see if it shuts of at a certain temp.

2004 GMC Sierra drivers side seat heater turnes on and off by itself


The seats are powered by a 30amp breaker which includes the circuits for the power motors.
The signal from the control switch goes to a door module then to a memory seat module, then to the heater elements.
It may be easier to disconnect the heating element for now, repairs will need a shop manual to test and trace the circuits.

Seat heater goes on by itself


You pretty much guaranteed have a bad switch for the heater, I'm afraid. If you don't want to buy an official replacement, a simple SPST or DPST toggle switch from Radio Shack would work.
