Original BMW Driver's Side Window Lifter Switch for BMW 325i, 328i, 330i, 335i, 335d, and M3 (2006–2012)

Mounted in the driver's door, this Original BMW window lifter switch 61-31-9-217-329 sends the signal that runs the power window motors on E90 and E91 3 Series cars, including the 325i, 328i, 330i, 335i, 335d, and M3. BMW names it the window lifter switch, driver's side, and supplies it in black. It weighs 114 g (0.3 lb) and is made in Japan. BMW's parts data shows production of this version beginning in February 2010.

Original BMW Parts carry a 24-month parts warranty.

This number supersedes the earlier switch 61-31-9-132-131, and BMW rates the change as exchangeable retrospectively, so the current switch also fits cars built before February 2010 that left the factory with the older part. Number 61-31-6-948-628 is also cross-referenced to this switch. A window switch is a set of buttons over electrical contacts, and on these cars the switch pack is rarely serviceable, so worn contacts, debris inside the mechanism, or failed backlighting are corrected by replacing the whole unit.

Common Questions

Will this fit my car if it has the older part number?
Yes. BMW lists this switch as exchangeable retrospectively with 61-31-9-132-131.

Can I replace just the backlight bulbs?
Switch packs are rarely serviceable, so restoring the lighting normally means replacing the unit.

Why does my window work only some of the time?
Dirt or a spilled drink inside the switch can cause it, though intermittent faults are more often the regulator and motor.
