Fix a stuck or slow-moving front right window with the Dorman window regulator and motor assembly, part number 751-856. This combined window regulator and motor assembly drops in as a direct-fit replacement for the front right position on the 2007-2015 Mazda CX-9, pairing the lift mechanism that raises and lowers the door glass with its drive motor in one unit. If a worn regulator or a failed motor is why the glass won't move, this assembly replaces both at once. See the Buyer's Guide tab for engine-level fitment.

  • Direct replacement: engineered to deliver the original front right assembly's operation across the listed applications.
  • Ideal solution: when a factory assembly fails from damage, fatigue or collision impact, this unit is engineered to help return the window to its original operation.
  • Durable construction: designed and manufactured to strict specifications for reliable performance.
  • Trustworthy quality: backed by a team of product experts in the United States and more than a century of automotive experience.

Which position does this assembly cover?

This unit is the front right window regulator and motor assembly. It does not cover the other door positions.

When should I replace the window regulator and motor?

Signs it may need replacing include a window that moves slowly, stops partway, will not move, or makes grinding noises. Diagnose the cause before ordering.

Does replacing this fix a window that won't go up?
