DRIVER HEATED SEAT SWITCH

For complete circuit diagrams, refer to Diagrams/Electrical.

CHECKING SWITCH SIGNAL AND WIRING AT THE DOOR MODULE

1. Disconnect and isolate the battery negative cable.
2. Access and disconnect the connector from the driver door module. Visually inspect wiring terminals for damage that would prevent positive connection. If not OK, repair or replace the necessary components.
3. Reconnect the negative battery cable and the driver door module. Turn heated seat on in the LO position. Using an Ohmmeter, check the resistance between the driver heated seat switch mux circuit and fused ignition switch output circuit. Resistance should be about 8 kilohms (8020 ohms ±4%). If not OK, check resistance directly at switch. If OK, go to STEP 4. If NOT OK replace the switch or faulty wiring.
4. Turn heated seat ON in the HI position. Using an Ohmmeter, check the resistance between the driver heated seat switch mux circuit and fused ignition switch output circuit. Resistance should be about 2.4 kilohms (2400 ohms ±4%). If not OK, check resistance directly at switch. If OK, go to STEP 5. If NOT OK replace the switch or faulty wiring.
5. With the system on in the HI position, Check for proper battery voltage and ground at the appropriate cavities. If OK, test heated seat element. If NOT OK, repair open or wiring short.
