Electrical Circuits
- With battery fully charged and all electrical connections cleaned and tightened, turn dome light on and operate seat switch. If dome light dims, seat may be jamming. Check for binding. If dome light does not dim, proceed with tests.
- Disconnect wiring harness at connector under seat. Connect 12-volt test light between Red and Black wire in female connector. If lamp lights, harness to seat is good. If lamp doesn't light, check for blown circuit breaker, continuity in Red and Black wires at connector, and for proper ground.
- Reconnect harness under seat. Remove switch from seat harness. To check rear motor of switch, connect a covered jumper wire between red terminal in center motor and either Light Blue or Orange connection in rear motor.
- Connect a second jumper wire between Black terminal in center motor and open connection in front motor.
- If motor does not operate, reverse jumpers in front motor. If motor still does not operate, the harness or complete 3-motor assembly is defective. To check center motor, connect a covered jumper wire between Red terminal of center motor and White or Tan terminal of center motor.
- Connect a second jumper wire between Black terminal of center motor and open connection in center motor. If motor does not operate, reverse White and Tan wires. If motor still does not operate, harness or 3-motor assembly is defective.
- To check front motor, connect covered jumper wire between Red terminal in center motor and Green or Yellow connection of rear motor. Connect second jumper wire between Black terminal of center motor and open connection in rear motor.
- If motor does not operate, reverse wires on rear motor. If motor still does not operate, harness or 3-motor assembly is defective. If all motors and seat operate properly, the switch is bad and should be replaced.
