Seat Heater: Testing and Inspection
Heated Seat Sensor
The wire harness connector for the seat cushion heating element and sensor are located under the seat, near the rear edge of the seat cushion frame.
1. Disconnect and isolate the battery negative cable. Unplug the 4-way heated seat cushion wire harness connector.
2. Using an ohmmeter, check the resistance between the heated seat switch output circuit cavity and the ground circuit cavity of the seat cover half of
the heated seat cushion wire harness connector. The sensor resistance should be between 2 Kilo-ohms and 200 Kilo-ohms. If OK, test the heated
seat control module as described. If not OK, replace the faulty seat cushion cover.
