Product Details

The Keystone MA1550128 is an OEM-replacement rear left (driver side) power window regulator with integrated motor, designed for Japan-built Mazda 3 vehicles (2014–2018). This direct-fit replacement restores smooth, reliable power window operation to the rear driver's door without modification.

Key Features:

  • Power-operated design – includes integrated motor for a complete, ready-to-install assembly
  • 2-pin connector – matches the factory wiring harness for a plug-and-play installation
  • Japan-built vehicle specific – engineered to match the OEM specifications of Japan-manufactured Mazda 3 models (not compatible with Mexico-built vehicles)
  • Left-hand / driver-side rear door fitment
  • OEM cross-reference: BHN9-73-590A (BHN973590A)

A worn or failed window regulator can cause the power window to stop moving, become stuck, produce grinding noises, or slip off track. This replacement assembly provides a precise fit and restores factory-level function. Compatible with 2014–2018 Mazda 3 and Mazda 3 Sport (Japan-built variants).

This company is super fast to get you your order! I ordered online and figured it would be at least a couple days or so until my order would even get processed. I think they overnighted it to me! The package showed up undamaged and sealed. Unfortunately, I may have to return the product as I am thinking I would like the spikes shorter but that is no fault of Thmotorsports. Hopefully their customer service is as superior as their ordering and shipping. At this point I would definitely shop there again and recommend them.

Thank you. You are cheaper than West Marine Pro, (although I have to pay shipping,) and faster than Amazon. My poor planning of immediate boat projects, and your products and ease of ordering and two day delivery work well.

great!

Thanks
