Restore smooth up-and-down travel to your front passenger glass with the Dorman window regulator, part number 741-640. This front right unit combines the window lift mechanism and its drive motor into one serviceable assembly, and it drops in as a direct-fit replacement for the 1999-2004 Oldsmobile Alero and 1999-2005 Pontiac Grand Am.
Sold as a single window regulator and motor assembly, it lets you replace the Dorman window motor and the regulator together instead of servicing them separately. If a slow, stuck, or dead front passenger window traces back to a failed motor or worn regulator, installing this assembly replaces both in one part. Diagnose the cause first, since switch and wiring faults can cause similar symptoms.
