Memory Function Switch
WARNING: This page is about a different car, the 2007 Pontiac Montana SV6, 2007 Chevrolet Uplander, and 2007 Buick Terraza. However, it is still accessible from the selected car via links, so may be relevant.
Ground is supplied at all times to the memory function switch from G301. When a memory recall switch is pressed, ground is applied through the switch contacts and the switch signal circuit to the memory seat module (MSM). The MSM then commands the appropriate seat motors to move to the pre-recorded seat position stored in memory in response to the switch signal.
