Seat Adjuster 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 is supplied at all times to the seat adjuster switch from the MEM Fuse located in the rear fuse block. When the seat switches are pressed they send a 12 volt signal to the MSM.
The MSM commands the selected seat motors to move in response to the switch signal.
