Front Left Window Motor and Regulator Assembly

Restore smooth power window operation with this TYC window motor and regulator assembly, part number 660166. It is a complete cable-style assembly with the motor included, built for the front left position on select Pontiac Grand Prix models.

  • Assembly - cable configuration for power window service
  • Front left mounting position
  • Complete assembly with motor included
  • Constructed from metal and plastic components
  • Direct replacement for select Pontiac Grand Prix applications

Vehicle Fitment

Compatible with 1997-2003 Pontiac Grand Prix, front left. This TYC 660166 window motor and regulator assembly is matched to the front left power window application on the Pontiac Grand Prix across the listed model years.

This part cross-references Dorman 741-647 for the same application.

How It Works

The regulator assembly guides the window glass through the door while the integrated motor provides powered movement. Using a complete cable-style design helps replace worn internal components in one service part, making it a practical solution for front left window repair on the Pontiac Grand Prix.

  • Window glass moves slowly, unevenly, or stops during operation
  • Motor runs but the window does not raise or lower correctly
  • Cable or regulator components are worn, frayed, or broken
  • Power window function is lost at the front left door
  • Original assembly no longer maintains proper glass alignment

Installation Notes

Install in the front left door only. Hardware is not included, and installation instructions are not included. Verify connector, mounting points, and glass alignment before final assembly. Because this is a cable-style power window regulator with motor included, careful positioning during installation helps ensure proper window travel.

Quality Assurance

TYC manufactures replacement electrical and body components for automotive applications. Part number 660166 is built as a complete assembly using metal and plastic materials to support dependable service in the specified Pontiac Grand Prix fitment.
