With controlled closure you keep the lock button on the remote pressed to wind the windows up. If you only want to half close them then you simply let go of the lock button before they are fully closed.
European Cars Are Great
With some European cars, such as Volkswagen and BMW it is possible to add remote window closure for no extra cost. As the car already has full closure built into the electrics it’s a nice upgrade to have it work with the remote.
The BMW 5 Series (E39) I worked on today is a good example. The alarm can even close the sunroof.
The other cool thing with late model BMW’s is that I know how to tap into the factory rear-view mirror LED. It normally only flashes with the BMW factory option alarm.
Of course, not all BMW’s have this option so it’s a great touch to get that O/E look. I first worked this trick out on a 3 Series (E46) about two years ago.
The video below shows the LED and some questionable fluffy dice!
Note: the LED is better seen at night, but I had to return the car!
