Dorman Power Window Lift Motor replacement for select vehicles — direct-fit, durable gearing (742-251)

The Dorman 742-251 Power Window Lift Motor is a direct-replacement window motor engineered to restore power window operation on compatible vehicle makes and models.

If your factory window motor has stopped working due to wear, collision damage, or electrical failure, this aftermarket unit is built to match the original's function and fit where specified. Dorman designs and tests its components to meet strict standards so you can regain smooth up-and-down glass movement without replacing the entire regulator assembly when not needed. Before ordering, use the vehicle lookup tool and confirm the "Confirmed Fit" indicator for exact compatibility; hover over any blue-circled “i” for fitment notes.

How does this motor compare to the original equipment motor?

This Dorman power window motor is manufactured to replicate the performance characteristics of the factory unit for the listed vehicles. It uses durable materials and tested components to provide reliable operation and similar torque output so the window moves as expected.

• Form, fit and function designed to align with original mounting points
• Electrical connector pattern matched for easy plug-in replacement
• Durable internal gearing to resist fatigue under normal use

What are the signs you need to replace a power window motor?

Common indicators include windows that no longer move, move slowly, or make grinding noises when activated. Intermittent operation or a motor that runs without moving the glass usually points to internal failure or stripped gear teeth.

• Window does not respond to switch commands
• Grinding, clicking, or abnormal noises during operation
• Motor runs but window remains stuck

How simple is the installation process for a DIYer?

Installation typically involves removing the door panel, disconnecting the electrical connector, and unbolting the old motor from the regulator assembly. Many enthusiasts with basic hand tools can complete the swap in an hour or two, but follow vehicle-specific instructions for steps like aligning the regulator and testing function before reassembly.

• Door panel removal and connector unplugging required
• Unbolt old motor, transfer any needed hardware, and mount the replacement
• Test window travel and switch operation before reinstalling trim

Will this part fit my vehicle and what should I check before buying?

Fitment varies by make, model and year — confirm compatibility using the store’s vehicle lookup tool and the Confirmed Fit bar. If the product page shows a blue-circled “i,” hover over it to read additional fit notes that could affect fit or require minor adjustments.

• Enter vehicle year, make and model into the garage tool to verify fit
• Review any fit notes shown by the blue "i" indicator
• Compare connector type and mounting orientation to the original part

Who is this for: The Dorman 742-251 Power Window Lift Motor suits DIYers, independent mechanics, and fleet technicians needing a dependable replacement motor for compatible vehicles. It’s a practical option when the motor itself has failed but the regulator and glass are intact, helping restore factory-like window operation without paying for a full regulator assembly.
