Circuit Description

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.

When the power seat switches are pressed they send a 12-volt signal through the switch signal circuit to the memory seat module (MSM). The MSM then commands the driver seat to move in response to the switch inputs.
