Product Details

ACI 81975 is a manual window regulator engineered for the front left position in select Toyota trucks and SUVs. It is listed for 1984-1989 Toyota 4Runner, front left, manual, without vent window, and 1984-1988 Toyota Pickup, front left, manual, without vent window. If you are replacing a worn Toyota 4Runner window regulator or a Toyota Pickup manual window regulator, this part provides the correct door-side service configuration with a hardened steel gear for consistent window movement. This part cross-references Continental WR40705 for the same application.

Common Problems It Can Help Solve

  • Window glass that will not raise or lower by hand crank
  • Rough, slipping, or uneven window travel
  • Stripped regulator gear teeth
  • Excessive play or binding in the door window mechanism
  • Failure of the original manual regulator assembly

Installation Notes and Tips

Verify front left door fitment, manual operation, and the no vent window configuration before installation. Transfer or source any required mounting hardware separately, since hardware is not included. Confirm the regulator matches the original Toyota 4Runner or Toyota Pickup door layout and window track before final assembly.

Quality Assurance

ACI identifies this window regulator as a new part that meets or exceeds OEM requirements. The hardened steel gear supports dependable mechanical operation in manual window systems.
