Lumbar Supports

Battery positive voltage (B+) is supplied at all times to the lumbar seat switch located in the seat from the IP fuse block PWR STS circuit breaker through CKT 1340 (ORN). Pushing the switch to inflate, actuates the lumbar air pump, which fills the lumbar bladder. Pushing the switch to deflate allows the bladder to deflate through the lumbar switch. The LH lumbar air pump receives ground from G202 through CKT t250 (BLK). The RH lumbar air pump receives ground from G201 through CKT 1450 (BLK).
