Dorman Rear Driver-Side Power Window Regulator & Motor Assembly — OE FIX, 2000–2007 Cadillac/Chevy/GMC Fit, Anti-Bind Cable Spring

The Dorman 741-578 is a rear driver-side power window regulator and motor assembly redesigned to prevent cable-reel binding and restore smooth window operation on select Cadillac, Chevrolet, and GMC models.

If your rear driver-side window has slowed, jammed, or stopped moving, the culprit is often a failing regulator cable that binds on the reel. Dorman’s OE FIX version upgrades the original design with cable tension springs and improved assembly tolerances to resist that failure mode. This replacement arrives as a complete regulator-and-motor unit, ready to swap into compatible vehicles listed below — check your vehicle trim with the garage tool before ordering.

How does this Dorman assembly stop cable binding?

Dorman addressed the common failure where the cable loses proper tension and jams on the reel. The OE FIX design adds cable tension springs and tighter tolerances so the cable winds and unwinds more consistently under motor load.

• Cable tension springs help maintain proper reel pressure under use.
• Redesigned cable routing reduces pinch and misalignment points.
• Factory-style motor integration ensures compatible power and fit.

Which vehicles will this part fit and how do I confirm fitment?

This assembly fits many Cadillac, Chevrolet, and GMC trucks and SUVs from the early 2000s through select 2007 models, including Escalade, Avalanche, Silverado, Suburban, Sierra, Yukon XL, and others. Always verify by inputting your exact make, model, and trim into the seller’s garage tool before purchase.

• Common compatible models: Escalade, Avalanche, Silverado, Suburban, Sierra, Yukon XL.
• Model years span primarily 2000–2007 depending on model and trim.
• Use the garage tool and "Amazon Confirmed Fit" bar to double-check notes and fitment.

What tools and skills are required for installation?

Installation is designed to be straightforward for an experienced DIYer or a professional technician. No specialty tools are required, but basic hand tools, trim removal tools, and electrical safety precautions will make the job easier and safer.

• Common tools: socket set, screwdrivers, panel pry tools, and gloves.
• Disconnect the battery before handling the motor wiring to avoid short circuits.
• Follow vehicle-specific service procedures for door panel removal and regulator torque specs.

What performance and reliability improvements can I expect?

Expect smoother, more dependable window travel and a lower risk of repeat failure from cable binding. The replacement is engineered in the United States and benefits from Dorman’s aftermarket experience for durability under daily use.

• Reduced likelihood of cable reel binding and unexpected window stops.
• Complete assembly replaces both regulator and motor for a full repair.
