Detailed Description

Dorman 748-200 is a replacement power window motor and regulator assembly for the front left door on 2005-2011 Cadillac STS vehicles. It is engineered to match the original regulator’s fit, function, and performance, making it a direct-service part for restoring proper window operation. This part cross-references ACI 382354 for the same application.

Use this assembly when the original window regulator or motor no longer moves the glass smoothly, loses express function, or fails to respond consistently. The integrated design helps simplify replacement on Cadillac STS front left window systems, and the micro-controlled motor with anti-pinch capability supports controlled operation during normal use. Part number 748-200 is also referenced as 15291744 and WLA4041 in interchange listings.

What It Helps Fix

• Window stuck in the up or down position
• Slow, erratic, or noisy window movement

• Motor failure or regulator wear
• Anti-pinch or control-related window operation issues
