Window Motor and Regulator Assembly

WAI part 88358 is a new power window motor and regulator assembly built for direct-fit replacement. It is engineered to meet or exceed OE manufacturing and performance specifications for Toyota Tacoma applications.

Key Features

  • New window regulator and motor assembly for power window repair

  • Motor and regulator included in one assembly

Detailed Description

This WAI window motor and regulator assembly is designed for Toyota Tacoma fitment and combines the motor and regulator into a single replacement unit. The steel gear design and precision-engineered construction support consistent window movement and proper alignment. Part number 88358 is a direct-fit solution for Tacoma models with front left and rear left applications, and it is built as a new assembly rather than a remanufactured unit. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Is Used For

  • Restoring a window that will not move up or down
  • Replacing a worn or noisy regulator mechanism
  • Addressing slow, uneven, or intermittent window operation
  • Repairing a failed window motor and regulator assembly
  • Correcting binding caused by worn internal components

Installation Notes and Tips

Fits 2005-2015 Toyota Tacoma, front left, and fits 2016-2018 Toyota Tacoma, rear left. Verify connector style, terminal count, and door application before installation. The assembly uses a bolt attachment type, and installation instructions are included. Part number 88358 should be matched to the vehicle’s original window regulator and motor configuration before replacement.

Quality Assurance

WAI states that this assembly is manufactured to meet or exceed OE specifications and is backed by a limited lifetime warranty.

This part fits 14 vehicles
