Power Seats: Testing: Motor

To test the front motor, connect a jumper wire between the red terminal and the green terminal of the switch connector. Connect a second jumper between the black terminal and the yellow terminal. Motor should operate. If not, reverse leads and test again. If motor does not operate, harness or motor is bad.
To test center motor, connect a jumper between the red wire and the tan wire. Connect a second jumper between the black wire and the white wire. Motor should operate. If not, reverse jumper connections. If motor still does not operate, harness or motor is bad.
