Electric Windows come down by themselves

HI, I recently had problems with my electric windows coming down by themselves, after I've locked up and walked away. A problem as you can imagine . Before I start playing around with relays and fuses, does anyone have any suggestions. I've got an Audi A3 97.
Thanks

I have the same problem with my VW Golf TDI 2001.

When I hit the remote control for opening my doors, the windows all come down and stop halfway down.

Don't know what causes this.

have you both put after market alarm systems in? that is kwhat normaly causes it

I have had the same problem - only three times in 6 years but still very worrying. I have locked my car and on two occasions I have found the driver's side door open (the next morning after about 10 hours) and the other time the passenger door (after only 2 hours). My A3 was first registered in 1999 - T registration. I look forward to hearing from anyone who has the same problem.

I had this problem yesterday morning. Found my car (Audi A2 -03) with both front windows down, parked in the street. Car radio missing, so very irritating. No forced entry shows on doors, windows or locks, so I suspect the electric windows came down by themselves and that some dishonest person took advantage of this to steel my radio. If someone knows causes or anything about this problem, I'm keen to know about it.

one of the answers to the windows opening is---.If you hold down the open door button for two or three seconds the door locks will open and the windows will start to go down how far down depends on how long you hold down the button.the same applies to when you lock the doors keep botton pressed and if your windows are open they will close.So if you come out and find your windows down the chances are that your button on the remote was pressed inadvertantly maybe while in your pocket.the only reason i know this is it happened me while standing next to the car (A4 AVANT 1.9tdi) windows just went down remote in pocket
