Passenger Power Seat

Passenger Power Seat Switch Test
The following procedure can be used to test the power seat switch on standard and quad cab models. Some quad cab trucks utilize a additional power lumbar option, if the switch being tested does not have the lumbar option simply ignore the lumbar portion of the test. For circuit descriptions and diagrams, refer to Wiring Diagrams.

1. Disconnect and isolate the battery negative cable.
2. Remove the power seat switch from the power seat.

If OK, see Power Seat Adjuster and Motors or Power Lumbar Adjuster and Motor in the Diagnosis and Testing Power Seat Motor.
If not OK, replace the faulty power seat switch unit.
