Dorman - OE Solutions Window Motor and Regulator Assembly P/N:748-546
Get your driver's window moving smoothly again with the Dorman window regulator and motor assembly 748-918, a direct-fit replacement for the front left (driver's) door of the 2004-2009 Nissan Quest. This single unit pairs the regulator mechanism with its power window motor, so a worn, seized, or damaged factory assembly can be swapped out in one part.
Signs the original may need replacing include a window that moves slowly, binds, drops off its track, grinds, or stops responding while the switch clicks. Because it ships as a complete Dorman window motor and regulator unit, you replace both wear points at once rather than chasing them separately.
