Windows Have A Mind Of Their Own Help!

Recommended Posts

Hi All,

I was hoping that somebody might have experienced the same problem that I am currently having with my 996tt..... I replaced the battery yesterday and also retro-fitted cruise control - now the windows seem to have a mind of their own and drop fully when I get in the car and turn the key.. I thought that was the only problem but I have just been out to my garage to find that once again both the windows have dropped all the way down. They operate normally and drop the usual small amount when getting in and out of the car. Please can anyone let me know if they have ever had or heard of this rather stange problem?? The cruise wiring is correct as I have doubled checked and had it operates as it should and the car did this before I had it coded for the new cruise items. Can replacing the battery cause this problem? I am going to do the reset procedure now on the windows but am worried about leaving the car anywhere now incase the windows drop! I have to say that this has not happened when it is locked so far - I am going to lock it inside the garage tonight to see if they do it......

Thanks, Jon

You will need to re-train the windows (and sunroof) after disconnecting the battery.

Hold the window button down until the window is all the way down - hold it an additional 10 seconds. Do the same for the window up.

That should do it.

thanks for the tip but I have already done this. I have just watched the car - once I put the windows up it only takes the car about 2 mins to put the windows down again - the interior lights come on and first the drivers window goes all the way down then the passenger one - I have tried locking it this time to see if it happens in this state! Am worried about parking it now!

So I have had the car locked for the last 2 hours and the windows have stayed up - I have now unlocked it and opened and closed the doors a couple of times and so far (only 15 mins) the windows have stayed up - hopefully I just needed to let the alarm reset itself or something as this is the first time that I have locked the car since changing the battery?

Yes I have had the same problem. Mine would drop when driving, when locking or even just walking away form the car. Started after a long spell of bad weather. Porsche Glasgow diagnosed faulty alarm module, damp in connectors.Replaced unit.

thanks frank, not sure if this is same or not - they always drop when I start the car now and I cannot control them until they are all the way down.... I have also noticed that when I put the key in the ignition and turn it on the cluster briefly says key not removed from ignition - odd as I do not remember this happening prior to replacing the battery?

It sounds the same. Always when starting but also driving around and also I would find the window or windows (could be both or just one) open in the morning or when I came back for shopping in the car park.

Can you pull the code from the DME . Do you know anybody with a Durametric?? Or take the car to your garage. If your windows open whilst left unattended I dont think your insurance will cover you!! I was more worried about the rain as I live in Loch Lomond Scotland :lol:

Having looked around I agree that it could be the same issue although mine have never opened as I am driving - or at least not yet! I think that I will ask a friend at my local opc to hook it up asap next week to see if they can see anything - so far it has not dropped the windows when the car is locked and luckily it is kept in the garage when I am not using it but my confidence is starting to drop as they seem to lower themselves randomly so next time it is locked I may come back to find them down!

Also did your interior lights come on when they lowered as mine do?

Thanks, Jon

Disconnect the battery again - wait about 2 minutes. After you re-connect start and run the car. Re-train the windows - then shut it off and lock it with the key.

If it does not work then - chances are your key button is sticking (internally) or there is an alarm problem.

Hi Jon,

I dont remember, the interior light did come on and stay on but I'm not sure when it did it, so I cant really help there. Pull the codes, I dont think disconnecting the battery is going to help but.... that's just my view. Why not try Lorens advice, if it works champion. If not still check the codes and go from there. I am not too sure if you will loose all the codes for the alarm after you disconnect. I say this because a Durametric will not reset " alarm " codes just read them I know I have one. My alarm had a sensor voltage failure at some point and I cant re set it. I have put a new battery on and it still wont reset but the sensor is now working. So i presume you might not loose all the alarm codes stored so far.

This is another one of those post that should be stored for future "Just in Case" so to speak.

Frank :)

Thanks Loren and Frank - I did disconnect the battery again, this time I left the key in the ignition as last time the alarm went mad for a while when replacing the battery.... When I reconnected the battery the windows both went all the way down immediately. I put the key in the ignition and turned it on then off and then locked the car with the key and held the key over until the windows closed. I then unlocked the car and have left it - so far the windows are now behaving!! Hopefully I had just confused the alarm system when I replaced the battery??

Thanks again for your inputs - I hope that the problem is now solved..... fingers crossed!

Unfortunately I spoke too soon!! I came out to my garage this morning and once again the windows were all the way down..... I didnt lock the car overnight so now it is locked in the garage to see if the windows go down locked - I want to see if I am safe leaving the car elsewhere than my garage! I think that it is time to visit my local OPC to see what they can find......

Hi Joh,

That's not so good then. :(

I still think it will be the alarm module. Your Porsche Garage will know. I didn't have to pay anything as I had an extended warranty so I dont know how much it will cost.

Let us all know what Porsche say.

Frank.

Once again thanks to everyone for their help but my problem is now fixed! In the end it seems the alarm just needed to reset itself as after a day and night of the car being locked the windows now behave just as they should! They have not gone down at all and everything is just right again.... I love these problems that fix themselves with no expense needed!!!

Hi John,

Thanks for updating us all.

Good result and one to bear in mind if it happens to anybody else.

Frank
