Question about Cars & Trucks
Heated seat (back only) started coming on by itself, I have unhooked the door control unit but it did not help, (now I can't turn it back off) thinking maybe just unhooking the back seat heater or pulling the fuse, as far as the fuse havent been able to locate fuse (need true labeling) can't find anything that says seat heater.
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.

I have the same problem except the back of mine works but the bottom doesn't. Passenger side is fine. Let me know what you find out if you could.

your heat/cool and vent selection options are controlled by engine vacuum through small clear tubes attached to the rear of your climate control interface. Other vehicles have small steel pull wires that operate the desired changes. You might try removing the trim and any fasteners affiliated with the interface/console. GENTLY pull outward and look to see if any of these tubes are pulled off or cut/damaged. Did anyone recently install a new stereo in the vehicle? If so, the vacuum tubing and or pull wires that change your outlets could have been damaged when the stereo unit was pushed into place. Hope this helps

Testimonial: "Very good information. THANKS!"
you have a couple of problems first of all your drivers sd=ide heated heat pad is probably faulty, for your heating problem you may have to get the hvac doors recalibrated.

SOURCE: heated, power seats not working
Check wiring under the seat. Frequent habit of pushing things under the seat such as flashlights and tools etc and moving the seat forward and back sometimes pulls wires or breaks them.
