OnStar® Button Assembly Replacement (Pickup)

WARNING: This page is about a different car, the 2002 GMC Sierra, 2002 GMC Cab & Chassis Sierra, 2002 Chevrolet Silverado, and 2002 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.

The OnStar® button assembly located on the rearview mirror can not be serviced separately from the rearview mirror. Should the button assembly need to be replaced, the entire rearview mirror assembly will need to be replaced.
