Guys please help :bangdesk:
I know the 2 Door M3's windows are supposed to close/seal/wind-up automatically when you close the door and the window is almost fully closed. But when this does not happen wht could be wrong?

The switch that controls the auto close could be on it's way out. They get worn.

Best fix would be to replace the switch.

Where is the switch located? Have you replaced yours before?

It is on the locking mechanism, not on the door but the car itself. It is a small black button type thing. By looking at it you should be able to see the wear.

i haven't changed mine, but it is not a big job.

Where are you based? i can have a look if you not too sure

when u push the switch on the lock the window should move up and the interior lights should turn off. its a switch behind the "bar"- in the picture below.

if that happens but there is still a gap- you will have to adjust the window itself, on the mechanism, there is an adjustment.

When u say it will move up, should it move up completely?

The switch controls that little up and down movement of the window when you open or close your door, which then gives you a tight seal with the rubber.

Experiencing the same thing in my coupe but not all the time. Sometimes the window winds up completely to seal and sometime the window dances up and down. On days when it's completely non-functional I push against the door to get it to seal (I have to do this at the car wash). Would this still be a worn switch or is something else out of alignment?

Sorry about the thread-jack Millas :rollsmile::rollsmile:

If you pushing the door and it then seals, it is the switch that is worn at the end.

You pushing enables the switch to go in completely.

Have a look at it, you will be able to see if it is worn.

what i did to my Coupe was get black double sided tape, cut it out and place it over the switch, when the door closes it then pushes the switch that extra bit so you dont have to replace the switch and i havent had a problem since.
i suppose you could even put something on the lock on the door itself to get it to contact.

the problem is the switch wears over time and doesnt make contact, this little fix pushes it that little further.

best of all you dont see the tape.

your window needs to be fully up for it to move, close it fully then push the sensor/button then your window will move that little bit. if your window is down that sensor will have no affect.

like Wykid said- its to seal the framless window against the rubber when closing the door.
