I don't recall ever being able to roll my windows up and down without having my key in the ignition and turned to at least the first power position, but my girlfriend noticed as she was getting out the other day that my 964 now does this.

I just tried it out again for myself... After letting it sit by itself all day, I unlocked the passenger side door and pressed the passenger window switch down. Sure enough the window went down and I'm standing there holding the key in my hand...

Is there something wrong or has this "feature" always been around and I just haven't noticed it.

Thnx,
Harry

This has happened to me several times. Haven't been able to figure out why this is possible.

My 928 does it sometimes too. I suspect a bad relay somewhere.

I will try it out right now for you.

Be Right Back

Yep, unlocked the car and sure enough mine work with the key in my hand too :-)

Euromagination

ah, cool... finally a problem that other people have so i don't look crazy!

incidentally, my horn stopped working recently too...

EDIT: ...and I have a very slow battery drain.

They will work with the drivers door open,

Ok what do I have to break to make my car do this? It drives me crazy when I shut off the car then my passenger jumps out and the power shuts off to the windows because a door has been opened. I would love to be able to do this.

Chad T,

If the door sensors were not working I doubt it would stop the windows for whatever the normal time period is after the ignition is off. So to fix that problem you could break the passenger side door open sensor. This would also cause your lights not to illuminate when that door opens and probably compromise your alarm. On the other hand it has taken me about 18 months to train my wife not to open the door till after the windows are up. (eventually I learned it was I that needed training by idling the engine for a bit before shutting off and rolling everything up during that time. Removes the exess oil in the crankcase as well.)

My car will not let me roll the windows up or down without the ignition on at least the first setting.

I had the same problem. It turned out to be the corroded door switches. I removed and cleaned the switches and all is fine. P.S. This problem also causes a battery drain.

Well I guess I better leave it alone. Just one of those annoying features like wipers that wipe the dry dirt on your windshield when you activate the washer spray way before any washer fluid hits the glass.

Sunroof can also be activated with drivers door open, along with the windows twas the same on my 964 and now on my 965.

Mine did this on day ONE, a bit disturbing at 1st, but I'm over it.

Thinking there is a relay issue or something related, have never addressed the "problem"...would like to hear if there is a simple fix though!

Does your interior light work when you open the doors? My car windows will work after the key is removed until a door is opened. Once that happens the windows loose power. I suspect one or both of your door open switches have failed.

Computamedic

I suspect we could all be talking at cross purposes here since I believe the operation of windows is a "market area specific" issue. AFAIK, European models allow the windows to operate indefinitely if either door is open.

I suspect there are different safety regulations applicable to different markets which determine how the windows (and plenty of other things) operate.

Sure, failure of door switches will affect the operation too but I think we are being optimistic to think there is a common problem - or a common solution.

Thnx for the replies so far...

Concerning my door ajar switches (which turn the dome lights on when a door opens), yes they do work; most of the time... The driver-side switch actually works about half the time and the passenger one works almost always.

I know we're dealing with a Porsche here, and I know they can have some weird electrical quirks (just like VW and Audi). That said, the main mystery here is: "How can a 'door open switch' confuse the car into thinking the key is in the ignition hours later?"

I can imagine the switch affecting the power windows when the key is in the ignition, but once the doors are opened, AND the key is out of ignition, AND the doors have been locked from the outside, shouldn't that sort of "reset" the power and tell the system to shut down?

I can think of some theories of how the switches may work but I'm not really sure. Can someone add to this for me?

Thnx,
Harry
