Dorman Rear Passenger Power Window Regulator & Motor Assembly 741-579 — Fits Select Cadillac/Chevrolet/GMC, Cable-Tension Anti-Bin

Dorman 741-579 is a complete rear passenger-side power window regulator and motor assembly engineered as an OE FIX replacement to prevent cable-reel binding and restore reliable window operation.

If your rear passenger window in a compatible Cadillac, Chevrolet, or GMC is sticking, drifting, or has stopped moving, this Dorman assembly replaces the entire regulator and motor with an improved design that resists the cable-binding failure common to some original equipment units. The assembly ships ready to install and was redesigned to add cable tension springs that reduce the chance of cable slippage or reel binding—two frequent causes of regulator failure.

How does this Dorman assembly reduce the common cable-binding failure?

Rather than a like-for-like copy of the factory regulator, Dorman re-engineered the cable system to keep constant tension against the cable reel. This prevents the slack and sudden snags that cause the cable to jam or fray. The reinforced reel and spring-loaded tension system increase operational smoothness during the whole travel cycle.

• Cable tension springs added to resist reel binding
• Reinforced cable routing to reduce wear points
• Motor matched to the assembly for consistent power delivery

Will this part fit my vehicle and how do I confirm compatibility?

This specific Dorman 741-579 assembly is manufactured to fit a defined range of Cadillac Escalade, Chevrolet Avalanche/Silverado/Suburban, and GMC Sierra/Yukon XL models and model years. Because trim and door options vary, always confirm fit by entering your exact make, model and trim in the seller’s garage or fitment tool. Also check any notes shown on the retailer’s fitment confirmation (for example an information icon may indicate additional fitment details).

• Compatible with select 2000–2007 Cadillac, Chevrolet, and GMC models (see fitment list)
• Use the garage tool to enter your trim and verify
• Review retailer fitment notes or "Confirmed Fit" indicators before purchase

How difficult is installation and what tools are required?

Installation is intended to be straightforward for anyone comfortable removing an interior door panel and swapping a regulator/motor assembly. Dorman’s design eliminates the need for specialty tools, though basic hand tools and common workshop equipment will make the job easier. If you’re unsure, a professional installer or a local shop can complete the swap quickly.

• No special or proprietary tools required
• Typical installation steps: remove door panel, disconnect electrical connector, unbolt and remove old assembly, install new unit
• Recommended: basic ratchet set, panel trim tools, and safety gloves

What quality and warranty expectations come with this Dorman replacement?

Dorman designs these OE FIX parts in the United States drawing on decades of aftermarket experience to address known failure modes from the original design. The assembly is built to deliver longer service life than the affected factory parts, but warranty terms and return policies vary by seller—check them before purchasing.

• Engineered enhancements over the original design for improved durability
• Backed by Dorman’s aftermarket engineering and quality controls
• Confirm seller warranty and return policy at checkout

Who is this for: The Dorman 741-579 rear passenger-side regulator and motor assembly is aimed at owners and technicians working on compatible Cadillac Escalade, Chevrolet Avalanche/Silverado/Suburban, and GMC Sierra/Yukon XL model years listed in the product fitment.
