Detailed Description

This window motor and regulator assembly is designed for the front right window on 2000-2001 Cadillac DeVille models. Dorman 741-521 replaces the original unit with a direct-fit assembly that follows the stock regulator’s geometry and operating requirements, helping restore normal window movement and motor operation. It cross-references ACI 82190 for the same application.

Use this part when the original window regulator or motor has worn components, broken gear teeth, or inconsistent movement. The bolt attachment style supports a factory-style installation, and the assembly is supplied with the regulator included for a complete replacement of the window lifting mechanism.

What It Helps Fix

• Window glass that will not raise or lower properly
• Grinding or slipping from a worn regulator gear
• Slow or uneven passenger-side window movement
• Motor failure that stops the window from operating
• Binding or sticking in the front right window track

Installation Notes and Tips

Verify the vehicle is a 2000-2001 Cadillac DeVille with front right application before installation. Compare the original connector, mounting points, and regulator layout to the replacement assembly before removal. Installation instructions are not included, and mounting hardware is not listed as included, so reuse or source the required fasteners as needed.

Quality Assurance

Dorman designs this replacement assembly to match the original part’s fit and function for the listed Cadillac DeVille application. The unit is extensively tested during development to support consistent operation in the intended vehicle fitment.
