I have a 2002 grand Caravan Sport and Just noticed that the air cinditioner is leaking water above the passenger floor board, where the lines pass through the firewall. I hoped it was just a plugged drain line (and may well be) but I got under and looked expecting to see an open ended line but found none. I'm not an experienced mechanic but i'd hoped to be able to fix it myself. Any idea what I'm up against?

 

Seal around the outside of the tube with silicon sealer from the engine side. The water just travels along the tube back into the interior.

 

Thanks, I'll give it a try.
