Lumbar Adjuster Relays

WARNING: This page is about a different car, the 2003 Pontiac Grand Prix. However, it is still accessible from the selected car via links, so may be relevant.

There are two lumbar adjuster relays, horizontal and vertical. Battery positive voltage is supplied at all times to both relays from the SEAT Circuit Breaker located in the IP fuse block. Ground is supplied to both relays through the relay ground circuit and G301. Each relay contains two coils and two sets of switch contacts. With the relay in the inactive or de-energized state, the lumbar motor control circuits are closed to ground through the relay switch contacts and the relay ground circuit.
