Power Lumbar Switch
WARNING: This page is about a different car, the 2002 Oldsmobile Aurora and 2001 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.
Battery positive voltage (B+) is supplied at all times to the driver and passenger seat lumbar switches from the PWR SEAT Circuit Breaker located in the rear fuse block. Both lumbar switches are grounded through the switch ground circuit and G 301. The lumbar switches provide both power and ground to the selected lumbar motors.
