Power Lumbar Seats

OPERATION
LH Circuit Breaker is hot at all times and applies voltage to the Left Lumbar Seat Switch.

The Left Lumbar Seat Switch controls both power to the Left Lumbar Pump motor and air flow to the Lumbar Bladder. Moving the switch in one direction powers the Left Lumbar Pump motor and, at the same time, routes compressed air to the Lumbar Bladder; the Lumbar Bladder inflates. Releasing the switch stops the Pump motor and closes the air passage to the Lumbar Bladder; the Bladder remains inflated.

Moving the switch in the other direction opens the air passage to the Bladder and the Bladder deflates; the Pump does not run.
