POWER SEAT SYSTEM

NOTE: For complete circuit diagrams, see Wiring Information. Wiring Information includes wiring diagrams, connector pin-out and location views, details of wire harness routing and retention, splice and ground locations and proper wire and connector repair procedures.

Operate the power seat switches and power lumbar support switch. Move the seat, seat back and power lumbar support in all directions. The seat and lumbar support should move in each of the selected directions. If any of the power seat and/or lumbar support motors fail to operate in more than one direction, proceed as follows:

1. Inspect the power seat and power lumbar motors to ensure the electrical connectors are fully connected to the motors. If OK, go to Step 2. If not OK, reconnect the electrical connector(s).
2. Check the power seat fuse in the Power Distribution Center (PDC). If OK, go to Step 3. If not OK, replace the fuse.
3. Remove the power seat switch and/or power lumbar switch from the seat cushion side panel. Check for battery voltage at the fused B(+) circuit cavity of the switch wire harness connector. If OK, go to Step 4. If not OK, repair the open circuit as required.
4. Check for continuity between the ground circuit cavity of the power seat switch and/or power lumbar switch wire harness connector and a good ground. There should be continuity. If OK, go to Step 5. If not OK, repair the open circuit to ground as required.
5. Test the power seat switch and/or power lumbar switch Power Seat Switch and Power Seat Lumbar Switch. If the switch tests OK, check the wire harness between the switch and the motor(s) (See Wiring information). If the circuits check OK, replace the inoperative power seat track and pan assembly or the seat back assembly. If the circuits are not OK, repair the wire harness as required.
