Product Details and Specifications

This Dorman window motor and regulator assembly (part number 751-657) features a combination of steel and plastic materials to balance strength and weight. The steel gear ensures durability under regular use, while the plastic components help reduce noise and friction. The assembly is designed as a non-express up or down electric motor, meaning it operates at a consistent speed without express functionality. It connects via a plug-in terminal with two terminals, simplifying the electrical hookup. The regulator is included, providing a complete solution for window movement. Note that mounting hardware and wiring harness are not included, so existing components should be reused or sourced separately.

Installation Notes and Tips

Installation of the Dorman 751-657 window motor and regulator assembly requires removal of the door panel and disconnection of the existing window motor.
