If your BMW X3’s rear passenger window is acting up – moving slow, making noise, or not moving at all – this NPAUTO Window Regulator could be the fix.

It’s a direct replacement for the rear right (passenger side) power window regulator on BMW E83 X3 models from 2004 to 2010.

This is the regulator assembly only – it doesn’t include the motor, so make sure your motor is still working.
It matches OE numbers 749-587, 51353448252, and 51353413190, meaning it’s built to the same standards as the original part.

Installation is straightforward if you’re handy, and once in, it should glide smoothly and quietly.

We stand behind it with a 2-year warranty, and our customer service team is ready to help if you have any questions.
Don’t let a stuck window ruin your drive.
Get this reliable, affordable regulator and restore your X3’s convenience and comfort.
Perfect for DIYers or mechanics looking for a quality replacement part.
