I've got a mildewy smell out of the trunk - and the sound deadening mat between the shocktowers is moist - every time it rains. It'll dry out and go away, but never ceases to come back. I've got a new trunk seal, and new taillight gaskets, and the license plate fasteners don't leak.
Any suggestions? Only thing I can think left to check is that the rear sunroof drain isn't blocked - but I don't know how to get at it to blow compressed air down it. Ideas?
