Dorman 741-578 Rear Driver Side Power Window Regulator and Motor Assembly | OE FIX for Cadillac, Chevrolet, GMC

Restore smooth window operation with the Dorman OE FIX 741-578

The original equipment window regulator can fail when the cable binds due to insufficient tension. This Dorman OE FIX replacement introduces a purposeful upgrade: built-in cable tension springs work to resist reel binding, promoting steadier glass travel and reducing the likelihood of intermittent movement.

This regulator and motor assembly is compatible with a broad range of GM full-size trucks and SUVs from the early 2000s, including Escalade, Suburban, Silverado, Avalanche, Yukon, and Sierra families. To ensure exact fitment, please enter your vehicle make, model, and trim into the garage tool before purchasing. If you see the Amazon Confirmed Fit bar at the top of the page with an 'i' note, hover over it to review any vehicle-specific notes.
