Replace a worn or broken front right (passenger-side) window mechanism with the Dorman - OE Solutions 740-645, a Dorman window regulator that raises, lowers and guides the door glass along its track. It fits many vehicles, among them the 1999-2006 Chevrolet Silverado 1500, 1999-2006 Chevrolet Silverado 2500 and 1999-2006 GMC Sierra 1500. See the "Vehicles it fits" section for the full list.
This is a power window regulator sold as the regulator only. The window motor is not included, so transfer your existing motor or buy one separately, following the vehicle service information.
- Trustworthy replacement: Dorman engineered and tested it to match the original window regulator's fit, function and performance on the listed applications.
- Quality assured: During testing it was cycled thousands of times in an actual vehicle door.
- Reliable design: It was engineered in the USA and draws on Dorman's long history in the automotive aftermarket.
- Easy installation: It was reverse-engineered to follow the original equipment's shape and dimensions for a direct fit.
A regulator may need replacing if the glass moves slowly or tilts, drops into the door, or won't move while the motor still runs. Grinding or clicking from inside the door is another sign. If a failed regulator is the cause, this Dorman OE Solutions window regulator replaces it. Check the motor and switch as well before you order.

It is the mechanism inside the door that moves the glass up and down and guides it along its track. On a power window, the motor drives the regulator.

Common signs are glass that moves slowly, tilts, drops into the door or won't move while the motor still runs, plus grinding or clicking noises. Diagnose first, as a motor or switch can also be at fault.
