Vehicle Application: Chrysler Town & Country 2007-03, Voyager 2007-03; Dodge Caravan 2007-03, Grand Caravan 2007-03 Each motor is tested 100%. Testing includes loading the motor on a simulated window fixture to verify speed and strength of the motor. For motors which have an auto up / down feature, output signals and pulse counts are matched to the vehicle application and motors are shipped in the ‘full up position’. Every motor has its internal components inspected and gauged. Bushings are gauged and re-impregnated with lubricating oil, ball bearings are replaced with new and armatures are fully tested to ensure insulation. Internal gears are gauged, inspected and renewed for reuse or replaced if out of spec. Replacement gears are redesigned with a stronger, less brittle material than O.E. to prevent premature wear, striping and breakage. Motor magnets are 100% recharged guaranteeing efficiency and reliability. Every remanufactured motor is assembled with the precise amount of lubricant to ensure quiet operation and long life. Every remanufactured motor is fully compatible with the O.E. mounting and regulator. As a remanufactured Original Equipment part, this unit guarantees a perfect vehicle fit.
