When I'm washing my max and make my way to drying out the trunk lines, I always get a little bit of drippage out of the cavity on the inside of the trunk lid where the Bose amp/active EQ pokes down (the black box under the speaker pod). I thought I'd ask here before grabbing my manual and going through it - is there a drain valve that might be plugged up that I can check for?

 

crawl in your trunk with a flashlight, then have someone spray water on your trunk, see where it is coming from or clogged. it's primative but it works.

 

put chalk all on the weather stripping, then close the trunk, and pour water on it,. then open, and wherever the chalk is washed away, thats your leak spot
