electric windows one-touch operation not working

Hi guys (and perhaps girls). My 02 996 is great but since Ive had it the windows have never operated on a one touch basis. The switch has to be held down until it has reached the desired position. Hardly a big complaint but might as well get it sorted. I read somewhere that it can be reset by holding the switch down for a short time after it has finished fully being raised or dropped. Unfortunately doing this has made no difference. Any suggestions? Thanks in advance

You have read the manual on the operation right? Answer "no" here I believe..... You will be expecting it to behave the same as every other car in the universe right where when you hold it down it goes into auto down? Right, well that's your downfall.... in the wonders of Porsche, you need to press it for less than 1/4 second pretty much. It will then auto down...Basically just click it and let it go, it should then go all down for you....It can take a bit of retraining to get it right I found.... Failing this, I can't help

Try what Jeff said first, but if that doesn't work: Lower the window fully, release the switch and then press the lower part again and hold for a second and release again. Then raise window fully by holding the button, and when it stops, release the switch and then press the raise part again and hold for a second and release again. They should now work in one-touch operation. If they don't, there are two possibilities: 1.) They have been programmed not to operate as one-touch windows for some reason by the workshop on the instructions of a previous owner 2.) They're buggered! :evil:

Cheers guys It was exactly as Jeff said. gumphh. Never encountered windows like them and I although i did check the manual some time ago my recollection was that it didnt say "hit the switch and hold for no more than 3 microseconds" Lol

I've done what 'Wattie' said to do, but I can only get my Driver's side window to operate one touch, on my 2004 996 C4S. Has anyone got both windows to operate one touch?

I Have a 2004 C4 and I have to press mine twice in quick succession to have them drop all the way.. hope that helps

I've now manged to get both front windows to go down with one touch operation, by following 'Watties' instructions, but should I be able to get them to go up with one touch? They don't at the moment. The Handbook is not clear on this. I suspect for safety reasons it's not going to be possible.

Is this the reset for the windows or just the reset for one touch operation? Johnbull, my windows go up & down with one touch but it is an earlier model than yours TB

I have heard that they don't remote close on facelift 996's, but didn't realise this also applied to one touch close from inside the car? However, if it is because they don't have an antitrap mechanism, it does make sense I'm afraid. However, it astonishes me that Porsche couldn't work out how to do that in 2004, when just about every other car manufacturer in the World has cracked that one! And they can't use the frameless windows as an excuse either, as my 2000 Audi TT had them, as did the Renault Avantime - with the largest frameless door windows ever fitted to a production car! (Mind you, being a Renault, they didn't always work, and a colleague still has the scars to prove it! )

My windows also both go up and down with one touch (but as per tbrown my 996 is earlier than Johnbull's), unless you turn the ignition off while they are going up or down, in which case you then have to hold the switch down to get them going up or down!

My car is an 03 (facelift) and the drivers window goes up/down with single press operation. The passenger side doesn't (but (IIRC) also has a different button indicating that it isn't automatic). This is a pain, so I'll see if I can programme it as well. Remote window operation. Holding the unlock button down (from locked), puts the windows down and the roof back. From unlocked, the roof and windows close. I have to hold my finger on the open/close button permanently though.
