Guide the front left door glass smoothly up and down its track with the Dorman window regulator 740-664, a power window regulator for the 1992-2011 Ford Crown Victoria, 1992-2011 Mercury Grand Marquis and 2003-2004 Mercury Marauder. It is sold as the regulator only; the window motor is not included.
The regulator is the mechanism inside the door that turns the motor's drive into the lifting and lowering motion of the glass. If a worn or broken regulator is behind a slow, tilted or dropped window, this unit replaces it.
- Built to the original: Dorman precision-engineers and tests this regulator to deliver the fit, function and performance of the stock unit on the listed vehicles.
- Cycle-tested: Run through thousands of cycles in an actual vehicle door as part of Dorman's quality checks, with a long service life as the goal.
- Engineered in the USA: Designed by Dorman and backed by its long history in the automotive aftermarket.
- Direct fit: Reverse-engineered to the shape and dimensions of the original equipment for a direct, seamless installation.
Signs a window regulator may need replacing include glass that moves slowly or crooked, grinding or clicking noises inside the door, or a window that drops and will not stay up. Because a failing motor or switch can cause similar symptoms, diagnose the cause before replacing parts.

Frequently Asked Questions
Is this the 1992-2011 Mercury Grand Marquis window regulator for the front left door?
Yes. It is cataloged for the front left position on the 1992-2011 Mercury Grand Marquis. The "Vehicles it fits" section shows every listed vehicle.
Will it work as a 1995 Ford Crown Victoria window regulator?
Yes. The 1992-2011 Ford Crown Victoria is a listed application for the front left door, so a 1995 model is covered.
Is the window motor included?
No. This is the power window regulator only, and the motor is not included. Follow the vehicle service information on whether the original motor can be transferred.
What does a window regulator do?
It is the mechanism inside the door that raises and lowers the glass and guides it along its track, driven by the power window motor.
What are signs the regulator may need replacing?
Slow or crooked glass travel, grinding or clicking in the door, or a window that drops can indicate regulator wear. Diagnose first, because a motor or switch fault can cause similar symptoms.
