Power Seat Motor: Testing and Inspection
Operate the power seat switches to move all three seat motors. The seat should move in each selected direction. If a motor fails to operate in only one
direction, move that seat a short distance in the opposite direction and test again to be certain the adjuster is not at its travel limit. If one or more of the
motors operate, see the diagnosis for the Power Seat Switch. If no motors operate, proceed as follows:
1. Test the circuit breaker in the fuseblock module as described. If OK, go to Step 2. If not OK, replace the faulty circuit breaker.
2
Remove the power seat switch as described. Check for battery voltage at the fused B(+) circuit cavity of the switch wire harness connector. If OK,
go to Step 3. If not OK, repair the open circuit to the fuseblock module as required.
3. Check for continuity between the ground circuit cavity of the 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, replace the faulty power seat adjuster and motors assembly.
