Replacement Details

Part number 740-812 is engineered for the rear right door on 2000-2005 Buick LeSabre vehicles with power windows. The regulator is extensively tested to align with stock-style fitment and operation, and it is listed with a plastic gear housing for this application. This part cross-references ACI 81235 for the same application.

Common Repair Applications

  • Rear window will not move up or down
  • Slow, uneven, or noisy window travel
  • Broken regulator gear or cable mechanism
  • Window drops into the door panel
  • Power window switch works but the glass does not respond

Installation Notes

Verify rear right door fitment before installation on your Buick LeSabre. This regulator uses a bolt-on design and requires reuse or separate sourcing of the window motor, since the motor is not included. No installation instructions are included, so compare the original unit and connector layout before removal.

Quality Assurance

Dorman manufactures this replacement regulator as a precision-engineered part that is tested to match the original equipment style of operation for the listed Buick LeSabre applications.
