Help get the driver's front window moving smoothly again with the Dorman - OE Solutions Window Motor and Regulator Assembly (P/N 741-178), a front-left power window regulator and motor assembly that drops in as a direct-fit replacement for the 2003-2006 Ford Expedition. It combines the lift mechanism and the electric motor in one unit, so when a factory assembly fails from damage, fatigue or collision impact, this Dorman window motor and regulator helps restore the original raise-and-lower operation on the front left door.
Direct replacement: designed to match the operation of the factory front-left assembly on the specified makes, models and years.
Ideal solution: when the original assembly fails, this unit is engineered to help bring back original-equipment window function.
Durable construction: built to strict specifications for reliable, repeatable performance.
Trustworthy quality: backed by a U.S.-based team of product experts and more than a century of automotive experience.
If your 2003-2006 Ford Expedition window regulator binds, moves slowly, drops off track, or the glass no longer responds to the switch, a worn regulator or motor may be the cause, and this assembly replaces both at once.
See the Buyer's Guide tab for the full engine-level fitment.
