Seat Track: Testing and Inspection

Operate the power seat switch to move all three seat motors in each direction. The seat should move in each of the selected directions. If the power seat track fails to operate in only one direction, move the seat track a short distance in the opposite direction and test again to be certain that the track is not at its travel limit. If the power seat track still fails to operate in only one direction, refer to Diagnosis and Testing of the Power Seat Switch. If the power seat track fails to operate in more than one direction, proceed as follows:
1. Check the power seat fuse in the power distribution center. If OK, go to Step 2. If not OK, replace the faulty fuse.
2. Remove the power seat switch from the seat. Check for battery voltage at the fused B(+) circuit cavity of the power seat switch wire harness connector. If OK, go to Step 3. If not OK, repair the open circuit to the power distribution center as required.
3. Check for continuity between the ground circuit cavity of the power seat switch wire harness connector and a good ground. There should be continuity. If OK, go to Step 4. If not OK, repair the open circuit to ground as required.
4. Test the power seat switch as described. If the switch tests OK, check the wire harness between the power seat switch and the motor for shorts or opens. If the circuits check OK, replace the faulty power seat track (adjuster) assembly If the circuits are not OK, repair the wire harness as required.
