Seat Track: Testing and Inspection

The following will determine whether or not voltage is continuous through the body harness to the switch.
1. Disconnect the power seat switch electrical connector (Refer to ELECTRICAL/POWER SEATS/ DRIVER SEAT SWITCH - REMOVAL).

2. Using a voltmeter, connect the ground lead to PIN B of the switch harness connector. Connect the positive lead to PIN A. If battery voltage is present, the ground and voltage circuits to the power seat switch are OK. Check the power seat switch for proper operation (Refer to ELECTRICAL/POWER SEATS/DRIVER SEAT SWITCH - DIAGNOSIS AND TESTING). If the seat switch checks out OK, remove the seat assembly and check the circuits from the power seat switch to the power seat track adjuster motors for proper continuity. If the circuits appear to be OK, replace the power seat track and adjuster motors as an assembly.
