Seat Adjuster Switch
WARNING: This page is about a different car, the 2006 Pontiac Montana SV6, 2006 Chevrolet Uplander, and 2006 Buick Terraza. However, it is still accessible from the selected car via links, so may be relevant.
The seat adjuster switch provides both power and ground to the selected seat motors. Battery positive voltage is supplied at all times to the passenger seat adjuster switch from the PWR SEATS circuit breaker located in the instrument panel (I/P) fuse block. The switch is grounded through the switch ground circuit and G302.
