seam
 on the drivers side. The sealant cracks, allows water in, then sits in the
channel
 inside at the seam. You need to recaulk where you see cracking, probably
right
 below the window where the body curves at a 45 degree angle.

actually forgot to mention that...pull away all the loose caulk (white seam
sealer) on the inside, where it is cracked/bubbled up, and then sand or dremel
grind it to shiny, extend, reseal w/ caulk or seam sealer, then undercoat...
as for the horizontal seam behind the rear wheels - the seam that is the panel
that water sits on when it rains in the rear vents - has anyone tried drilling
holes in the bottom of this panel, to facilitate the exit of water??
