WARNING: This page is about a different car, the 2008 Buick LaCrosse and 2008 Buick Allure. However, it is still accessible from the selected car via links, so may be relevant.
The driver and front passenger seat adjuster switches are supplied battery positive voltage at all times from the PWR SEAT circuit breaker located in the I/P fuse block. The seat adjuster switches provide both power and ground to the selected seat adjuster motors. The seat adjuster switches are grounded through the switch ground circuit at G 301.
