Original BMW Driver's Side Window Switch Panel for BMW 3 Series E90/E91 and M3 (2006–2012)

Mounted in the driver's door, this Original BMW window lifter switch is the black switch panel the driver uses to run the power windows on the E90-generation 3 Series, from the 325i and 328i through the 335i, 335d, and M3. A window switch sends current to the window motor, which drives the regulator to raise or lower the glass. BMW's part data shows this number in black, sold as a single piece weighing 111 g (0.2 lb), with production starting in February 2010. It is made in Japan.

Original BMW Parts carry a 24-month parts warranty.

Part number 61-31-9-217-326 supersedes the earlier driver's switch 61-31-9-155-501, and BMW rates the change exchangeable retrospectively, so cars built before 2010 take this newer switch as well. BMW applies it to both the E90 sedan and E91 wagon, before and after the facelift, across N51, N52, N54, N55, M57N2, and S65 engines. Common switch failures include worn electrical contacts, debris or spilled drinks inside the mechanism, and internal circuit faults. A switch that feels loose or no longer clicks points to mechanical wear, and dead backlighting is another sign.

Common Questions

Which door does this switch go in?
It is the driver's side switch panel, finished in black.

My car was built before 2010. Will this fit?
Yes. It replaces 61-31-9-155-501 and BMW rates the change exchangeable retrospectively.

The window only works sometimes. Is it the switch?
Dirt in the switch can cause it, but intermittent operation is more often the regulator or motor, so test the motor first.
