Product Details

The ACI 380198 is a front left power window regulator engineered for the Mazda 3 platform from 2010 through 2013, including Mazda 3 Sport applications. As a window regulator, it controls the up-and-down movement of the door glass through the vehicle’s power window system. The plastic gear design supports the regulator’s drive function while keeping the part aligned with the original power-operated setup.

ACI’s Window Regulator line focuses on replacement components for door glass operation, and this part is listed for the front left position only. If you are replacing a failed regulator on a Mazda 3 or Mazda 3 Sport, confirm the vehicle’s trim and door position before ordering. This part cross-references WAI WPR6130L for the same application.

Common Problems This Part Can Address

  • Window glass that will not move up or down
  • Slow, uneven, or jerky window travel
  • Grinding or slipping sounds from the door
  • Window dropping inside the door panel
  • Failure of the original power regulator mechanism

Installation Notes and Tips

Install this regulator in the front left door only. Because the motor is not included, reuse the existing motor only if it is in proper working condition or replace it separately as needed. Verify connector style, mounting points, and glass alignment before final assembly. After installation, test full window travel to confirm smooth operation and proper indexing.

Quality Assurance

This is a new ACI replacement part built for the specified Mazda 3 and Mazda 3 Sport applications. It is listed under ACI part number 380198 and supported by the provided interchange references for application matching.
