I have a 1999 a4 2.8 recently the car seems to roll the windows down on its own and unlock the doors. I went away and when I got back I noticed that the windows were down and the battery was dead, I charged the battery and rolled the windows up as soon as I closed the door the windows rolled down. The door lock switch no longer works and I can't roll the windows up or down using the keys. I noticed that whenever I would used the doorlock switch I would here like a vacumm pump in the trunk no longer here that. If anyone has some suggestions on what it could be I would highly appreciate it.

 

Help if you could VAG it and get us the code man. Possible just shitty connections but dont know... Trial & error.
