Switch, Seat, Power: Operation: Operation

When a power seat switch is actuated, a battery feed and a ground path are applied through the switch contacts to the selected power seat adjuster or recliner adjuster motor. The selected seat adjuster motor operates to move the seat or recliner through its drive unit in the selected direction until the switch is released, or until the travel limit of the adjuster is reached. When the switch is moved in the opposite direction, the battery feed and ground path to the motor are reversed through the switch contacts. This causes the seat adjuster motor to run in the opposite direction.

On vehicles equipped with the memory seat system, the driver memory seat switch provides a resistive signal/input to the Memory Seat Module (MSM). The MSM is responsible for the 12 volt battery feed and ground path to the power seat adjuster motors.

No power seat switch should be held applied in any direction after the adjuster has reached its travel limit. The power seat adjuster motors each contain a self-resetting circuit breaker to protect them from overload. However, consecutive or frequent resetting of the circuit breaker may result in motor damage.

The individual switches in the power seat switch cannot be adjusted or repaired. If a switch is damaged or inoperative, the entire power seat switch must be replaced.
