Dorman - OE Solutions Window Regulator P/N:740-122
Dorman 740-171 rear right window regulator for the 2003-2006 Ford Expedition and other vehicles raises and lowers the glass in a power-window door. The original regulator fails when its plastic window slide block fatigues and cracks, and this one has a redesigned slide block.
A window that moves slowly, stops partway or drops inside the door can mean the regulator has failed. The window motor, the switch or the door wiring can be behind those signs too, so find the cause before buying. This listing is one regulator for the rear right door; the 2003-2006 Ford Expedition takes one on this side, and the rear left door is a separate part.
This window regulator fits the 2003-2006 Ford Expedition and the 2003-2006 Lincoln Navigator.
