Complete window motor and regulator assembly for front and rear doors—direct replacement for A4, S4, and RS4 models. Built to OEM specifications, this set handles the full lift-and-lower cycle without the seized or sluggish operation that plagues aging regulators. Quality construction ensures smooth, quiet operation across thousands of cycles.
Will this bolt straight into my car, or do I need new fasteners?
The regulator and motor mount at factory attachment points using existing hardware. You won't need additional fasteners unless yours are corroded or damaged—inspect your old assembly before installation to confirm.
Do these come with the window glass or connector harness?
The set includes the motor and regulator assembly only. Your window glass and electrical connector stay with your car—no removal or transfer needed on your end.
How do I know which window (front or rear) this is for?
You'll need to match the assembly to your specific door location before ordering—this set covers one window position. Check your order confirmation or reach out before purchase to confirm front vs. rear fitment.
