I just got an A4 1999 quattro 100K miles in November 2008. My power locks, power windows sun roof and alarm system all stopped working at the same time. I have done everything to try to fix it but i havent met with any success.I took the car to Audi dealership where I paid alot of money for their services but all i got was a long list of items to buy...I am student so i decided to keep using the car that way.I was almost giving up on the whole situation when 5 days ago, after a heavy rainfall,everything started working again.
I was so excited.My joy knew no bounds.
while driving on that fateful day..i noticed that my interior light started blinking and the windows were going up and down. 15 minutes after parking my car, the hazard light started blinking on its own.
2 days after, everything stopped working again.
I am really at a loss as to what to do....I am so confused.
I am hoping someone can help with this problem so i can sleep peacefully again

thanks.
