Get the driver's door glass moving again with the Dorman window regulator and motor assembly (P/N 741-637), a front left replacement for the 1997-2005 Buick Century, 1997-2004 Buick Regal, and 1998-2002 Oldsmobile Intrigue. This single unit pairs the electric window motor with the regulator mechanism that raises and lowers the door glass, so a failed factory assembly can be swapped out complete. See the Buyer's Guide tab for engine-level fitment details.
Because the Dorman window motor and the regulator arrive as one pre-assembled part, you replace both the drive and the lift mechanism in a single job. If your Buick Century window motor no longer moves the front left glass, or the glass drops or binds in the track, this assembly addresses those signs of a worn regulator and motor.
