Detailed Description

When a power window stops working because the motor is worn out, this Dorman window motor provides a replacement built to match the original unit’s fit and function. It is designed for select Ford Explorer, Ford Taurus, Mercury Mountaineer, Mercury Sable, Ford Explorer Sport Trac, Ford Explorer Sport, and Lincoln Continental applications, with coverage for rear right and front left positions where listed. Part number 742-277 is also cross-referenced to Cardone New 82-307 for the same application.

Because the wiring harness is included and the unit uses a plug-in connection, this replacement is suited for vehicles where the original motor and gear assembly need to be restored without changing the regulator. The included window lift gear supports proper engagement with the existing window mechanism.

Common Problems It Can Solve

• Window glass will not move up or down
• Slow or weak power window operation
• Motor noise without window movement
• Intermittent window function from a worn motor
• Failed rear right or front left window motor in supported applications
