LKQ WST010212 Door Window Belt Weatherstrip

The LKQ WST010212 is a door window belt weatherstrip, also commonly referred to as a window belt molding or inner/outer door glass seal. This component runs along the top edge of the door panel where the window glass meets the door frame, forming a flexible seal that keeps out wind, water, dust, and road noise as the window moves up and down. Over time, belt weatherstrips can crack, shrink, or pull away from the door, leading to air and water leaks, wind noise, and potential damage to the window glass or regulator. Replacing a worn strip restores a tight, clean seal and helps protect the interior.

Part number WST010212 fits select 1999–2006 GMC, Chevrolet, and Cadillac models across 120 vehicle applications.
