Front Left Power Window Regulator (No Motor) For BMW E83 X3 2003-2010 – Driver Side

If your driver side window in a 2003-2010 BMW E83 X3 isn’t rolling up right, this might be the fix.

It’s a brand new front left window regulator, no motor included—just the mechanism.

The part number is 51333448249, and it’s a direct fit for that model.

It’s unbranded but meets OEM specs, so it should slide right in and work like the original.

If your motor is still good, this saves you from buying a whole new assembly.

Straightforward swap, gets your window working again.
