Hi Guys,

I had my car broken into and they gained entry by smashing the drivers window. I've replaced the drop glass without too many dramas (and with the help of some excellent articles on here) but I still have one problem. When the door glass is down and I try to raise it using the 'one touch' of the window switch, it rises about half way and then returns to the down position. A friend said he had a similar problem with an Audi he owned previously and he thinks there is an 'air switch' which needs to be be reset when you replace the glass. Can anyone give me some advice before I have to resort to giving the local dealer my kidney to fix it?

Thanks for any help you can give.


Bob.

Might be the same process as when you disconnect the battery. IIRC you close the window, then manually hold it down to open it, and then manually close it again after which the auto function should know the limits.

I don't know what "air switch" is but on BMW there is a control module that controls the windows (and other convenience features) and knows the window position by tracking the circuit load. In case some changes are made, this module needs to learn again where is up and down of the window. I am pretty sure it is the same for Porsche (and many other cars). There is a simple process of doing that but it has been a while. Do a search and I am sure you will find it.

Thankfully there was nothing in it to steal except some parking change, which they didn't find. However, the cost of both the door glass and rear quarterlight glass (which they also smashed for no apparent reason) was costly enough. My neighbour lost some expensive sunglasses and an Ipod from his Mercedes, so he wasn't so lucky.
