Driver's side seat heats up and cycles

Hello,

This happens when the seat heater control module goes out located in the drivers seat or in the drivers door. Here is its location (below). Once you replace it you may need to have it reprogrammed.

Here is the seat heater wiring diagrams so you can see how the system works.

Check out the diagrams (Below)

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken

I had this problem and it was the modules in the drivers door

The HEAT on the drivers side seat will not work. When you first turn it on it stays on for about 15 seconds and then you hear a click and it shuts off. After that, it will only stay on for less time until finally only it stays on for about 2 seconds. The Heated Seat on the passengers side works fine for ever, BUT if you turn on the Drivers Heated Seat, it will TRIP the Passengers Seat when it trips.

NEED HELP as it is getting Winter and I love my heated leather seats. I am an Engineer so I should be able to figure this out, but if someone else has already solved the same problem I am not too proud to learn from them.

Thanks,

- Move driver seat all the way forward.
- raise electric seat base up.
- From the back seat area, look for a grey 6 pin connector left of center under seat.
- Disconnect the connector
- Measure the ohms using your resistence meter set to lowest setting.
- Measure the seat cushion Terminal A brown to Terminal F black (1.5 to 5.5 ohms).
- Measure seat back Terminal C yellow to Terminal D black (1.5 to 5.5 ohms).
- If outside than range...replace!

It sounds as though a circuit breaker is tripping. Or the heater is drawing more current than either the fuse or relay can handle.
