[s-cars] Sunday hose question

[Paul DAnneo]

Happy Sunday All,
   
  I was greeted this AM with a dead battery. '93 S4.
   
  I pull the back seat bottom for the first time in a few years and have found a hose is disconnected and I can't find from where.
   
  It's a clear hose coming out of the bottom of the seat pan. Directly behind the battery. At its end is a 90 deg. barbed elbow. That is where it ends. 
   
  Also, which is the remote entry control?
   
  Thanks,
   
  Paul
   
  p.s. I tried searching the archives and couldn't get much.
         then I tried the AW site and got alota bs and swearwords regarding a toilet and no toiletpaper...
