Product Details

Cardone Power Window Motor 42-3050 is built as a remanufactured OE replacement for rear left window service. The motor is re-engineered from an original equipment core, with bushings re-impregnated, bearings replaced as needed, gears inspected and renewed, and lubricant applied in the correct amount for quiet operation and long service life. For vehicles with auto up/down functions, output signals and pulse counts are matched to the application so the motor can work with the factory window control strategy.

This part cross-references Ford 4L2Z7823394AB and Mercury 4L2Z7823394AB for the same application. It is a strong match for owners searching for a rear left power window motor for 2004 Ford Explorer, 2004 Mercury Mountaineer, or 2004-2005 Lincoln Aviator.
