Power Lumbar Operation Oldsmobile w/AL2

The LH and RH power lumbar system each consist of the lumbar switch and the lumbar air pump. The lumbar switch, located on the outboard side of each seat, directly controls the lumbar air pumps located under the seat. Pushing the lumbar switch to inflate, actuates the lumbar air pump, which fills the lumbar bladder. Pushing the lumbar switch to deflate allows the bladder to deflate through the lumbar switch.

Power Lumbar Operation Pontiac w/AL7

The sport seats incorporate a power inflate/power deflate pneumatic system used for controlling the comfort features of the seats by inflating or deflating air cells within the seats. The pneumatic system consists of the console seat switch, seat air pump, seat air control module, and the seat cushion air valves.

Set the seat select switch to the LEFT or RIGHT position whenever an adjustment is to be made. All four of the comfort feature switches operate in a similar manner. If any one of them is moved to the INFLATE position the seat air pump is operated which fills the lumbar bladder. When any one of the switches is moved to the DEFLATE position the seat air pump is operated to deflate the bladder.
