Driver Heated Seat Switch

Inspect the Heated Seat Switch for apparent damage or sticking/binding condition, replace if necessary. Refer to Heated Seat Switch Removal and Installation. For circuit description and diagrams, refer to Wiring.

1. Remove the heated seat switch from its mounting location. Refer to Heated Seat Switch Removal and Installation.
2. Using an ohm meter, check the ground circuit cavity of the heated seat switch electrical connector for a good continuity to ground. If OK, go to Step 3. If not OK, repair the open ground circuit as required.
3. Turn the ignition switch to the RUN position. Using an volt meter, check the 12v (B+) circuit cavity of the heated seat switch electrical connector for 12v. If OK, go to Step 4. If not OK, repair the open or shorted 12v B+ circuit as required.

4. Turn the ignition switch OFF. Using an ohm meter, check the continuity between pin 4 and pin 6 of the heated seat switch, while in its neutral, LO and HI positions. Measure the resistance between the two pins and compare with the chart. If the readings do not correspond to those in the Heated Seat Switch Continuity table, replace the heated seat switch.
