Lumbar Seat

Circuit Breaker H is hot at all times and applies voltage to the Passenger's and Driver's Power Lumbar Switches.

The Power Lumbar Switches control power to the Lumbar Seat compressor and the release of air pressure from the Lumbar Seat bladders.

Moving the switch in one direction powers the seat compressor motor, and the Lumbar Seat bladder inflates. Releasing the switch stops the motor and closes an air bleeder valve in the switch. The seat bladder remains inflated.

Moving the switch in the other position opens the air bleeder valve, and the bladder deflates. The compressor does not run.
