Tackle a stuck, crooked or slow front right window with the Dorman window regulator 752-856, the power window mechanism that carries the door glass up and down. It installs as a direct-fit replacement for the 2007-2015 Mazda CX-9. If a worn or broken regulator is behind the problem, this unit is a front right window regulator replacement for the 2007-2015 Mazda CX-9, engineered around the original design.
This part is sold as the regulator only, so the window motor is not included. If your current motor works properly, it can be moved over to the new regulator. Otherwise, purchase a motor separately.
- Built to match the original: Dorman engineered and tested it to replicate the original window regulator's fit, function and performance on the listed vehicles.
- Cycle-tested: Dorman ran it through thousands of up-and-down cycles in an actual vehicle door.
- Engineered in the USA: It was designed in the USA and is backed by Dorman's long history in the automotive aftermarket.
- Direct fit: It is reverse-engineered to follow the original equipment shape and dimensions for a direct, seamless fit.
A window regulator may need replacing if the glass moves slowly, sits crooked or drops into the door. Other signs are grinding or clicking inside the door when you press the switch, or a window that won't move even though you can hear the motor run. A failed motor, switch or wiring fault can cause similar symptoms, so diagnose the cause before replacing parts.
