If a worn or failed switch is why your front left window won't move on command, the Standard Ignition switch DWS-128 is designed to replace it. This power window switch is designed specifically for Ford vehicles and serves as a direct-fit replacement in the front left position of the 2004-2008 Ford F-150 and the 2004 Ford F-150 Heritage.
A power window switch controls the window motor circuit, raising or lowering the glass when you operate it. Signs this switch may need replacing include a front left window that doesn't respond, works only intermittently, or moves in one direction only. The window motor, regulator or wiring can cause similar symptoms, so diagnose the cause before replacing the switch.
See the "Vehicles it fits" section for complete fitment details.
