A-Premium Power Window Regulator Rear Passenger Side for BMW E90/E91 — Without Motor, OE-Fit

If your BMW E90 or E91 rear right window slides slowly, binds, or drops because the regulator is worn or damaged, this OE-style replacement restores proper operation. Engineered to match factory mounting points and cable paths, the assembly installs in place of the original regulator and is compatible with sedans and station wagons produced from 2007 onward.

How will this regulator improve my rear passenger window's performance?

This regulator replaces the worn mechanical components that control vertical glass travel, removing slack and uneven motion. With the correct cable routing and attachment points, it brings back stable, quiet operation so the window raises and lowers evenly.

• Direct OE-fit design for correct alignment and smooth travel
• New cable pulleys and carriers reduce binding and noise
• Durable stamped arms and guides resist premature wear

Which BMW models and body styles will this part fit?

The unit is specifically made for BMW E90 and E91 models and matches the dimensions and mounting used on late‑model 3 Series cars. It’s intended for rear right (passenger side) installation and is suitable for either the sedan or the station wagon configuration.

• Compatible: BMW E90 / E91 series from 2007 onward

Will I need any special tools or electrical parts to install it?

This part is supplied without a motor, so you reuse the existing motor or purchase a separate motor if your original is faulty. Installation requires basic hand tools and interior trim removal tools; familiarity with door panel removal and window alignment is helpful for safe, correct fitment.

• Reuses original motor; motor not included
• Standard socket set, screwdrivers, and trim pry tools recommended
