How can I deactivate Window Auto Roll Down When the doors open?

Hey everyone, I live in MN and It is freezing tonight.. I have 04 330ci Uplift and As you coupe owners know that we have these window auto roll when the doors open.. But the winter is here and i don't wanna damage the glass or the window motor. So is there anyway I can deactivate this option for the winter??

Thanks

You are not gonna hurt the glass, and it seems to me that BMW woulda thunk of what happens when it is cold outside, especially since most cars spend their entire lives outside, well outside or in the garage, but almost never in the living room.

Keep the weather strip clean, and it should be fine. Having said that, I've heard that if you flick your nipple in the right conditions in Minnesota, it will shatter. The whole point of having thte window drop is so that it will clear the weather strip. If the window does not drop, won't it get wedged on the weather strip? And, won't this do more damage than letting the car operate as designed?

I would expect you will not damage the glass or the windows motor as I would assume that the pinch protection, which is actually current draw based, will shut the motor off it the window does not move??

I think BMW being a German car company has probably thought through the issue of ice and snow.

Not 100% sure if PA Soft can turn off the window drop function, the 3/8"-1/2" drop of the window is also on the convertibles as well.

I have an 05ci and how do you think your door is going to open if the window doesn't drop? The glass sits up inside the roof when the door closes so I don't see how you would make that work even if the scanner **** it off...

Nick_M3's correct. If you have a coupe or convertible, bmw designed the driver and passenger windows to roll down when the door is open and roll up to sit in a track when the door is closed. This is for additional stability,

you risk damaging or shattering the glass if the window doesn't roll down before opening or closing the door.

My window had ice built up last winter and I didn't clean it off properly. The window did not roll down far enough when I opened the door (though it opened). When I went to shut the door, the window snagged on the chrome trim piece and prevented the door from closing.

Is freezing to the rubber seal the problem you're trying to solve? Drop or not, it's still just as likely to freeze to the seal. Put some kind of rubber dressing on it.

Keep your ice scraper in the trunk. When you get ice that jams the window, use it. Otherwise let it do it's thing. It needs to go up and down to clear the molding.

Even if you open the door and it is frozen, its fine. Blast the heat and put the vent directly on the window, you'll be fine in no time.

Unplug the battery for about 20 minutes. It'll disable it when you plug it back in. You can reactivate it by holding the button down for 20 seconds, then up for 20 seconds.
