Power Seat Motor: Testing and Inspection
Power Seat Adjuster and Motors
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
adjuster fails to operate in only one direction, move the adjuster a short distance in the opposite direction and test again to be certain that the adjuster is
not at its travel limit. If the power seat adjuster still fails to operate in only one direction, see Power Seat Switch in the Diagnosis and Testing. If the
power seat adjuster fails to operate in more than one direction, proceed as follows:
1. Test the circuit breaker in the junction block as described. If OK, go to Step 2. If not OK, replace the faulty circuit breaker.
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 junction block 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 for the inoperative power seat motor(s) between the power
seat switch and the motor for shorts or opens. If the circuits check OK, replace the faulty power seat adjuster and motors assembly. If the circuits
are not OK, repair the wire harness as required.
