Designed to help resist the stretched-cable failure Dorman identifies in the factory unit, the Dorman power window motor and regulator assembly 741-644 is an OE FIX replacement that raises and lowers the front left door glass. It fits many vehicles as a direct-fit replacement for the listed applications, 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 and engine details.
Dorman notes that the original equipment window regulator fails when its cable stretches over time. This OE FIX redesign adds cable guides and sheathing to help resist reel binding, so this window regulator and motor assembly offers upgrades over the factory part.
This assembly may need replacing if the window moves slowly, stops partway, drops into the door, or grinds or clicks when you press the switch. A faulty switch, fuse or wiring can cause similar symptoms, so diagnose the cause before you replace the assembly.
Will this work as a 1999-2006 Chevy Silverado 1500 window motor replacement?
Yes. Dorman 741-644 is listed for the front left door of the 1999-2006 Chevrolet Silverado 1500. Check the "Vehicles it fits" section to confirm your exact truck.
What does this Dorman window motor assembly do?
It pairs the electric motor with the regulator mechanism that raises and lowers the front left door glass when you operate the window switch.
How is this Dorman window regulator different from the original?
Dorman says the factory regulator fails as its cable stretches. This OE FIX version adds cable tension springs, cable guides and sheathing to help resist cable reel binding.
What are signs this assembly may need replacing?
Watch for a window that moves slowly, stalls partway, drops into the door, or grinds and clicks. A switch, fuse or wiring fault can cause similar symptoms, so diagnose the cause first.
Does it also fit the 1999-2006 GMC Sierra 1500 and 1999-2006 Chevrolet Silverado 2500?
Yes. It is listed for the front left door of the 1999-2006 GMC Sierra 1500 and the 1999-2006 Chevrolet Silverado 2500. See the "Vehicles it fits" section for other models.
