I redid the plastic liners on the two rear doors on my 85 Jetta GL with
6-mil plastic and 3-M weatherstrip putty. I dried the bottoms of the door panels with a heat gun and put duct tape on the chewed up cardboard and closed everything back up.
I was very careful to fully seal the door openings with plastic, cutting only small slits for the crank handle and a minimum cutout for the inside door handle.
I thought I'd solved the problem of leaking into the rear set wells. Not so. As nearly as I can tell, my fix accomplished nothing. The first time I drove it in the rain, I had another half-inch of standing water in the back seat, and soaking wet door panel bottoms.
Any idea what to try next? I live in Juneau, Alaska now, and I either have to solve this problem or take the car to Arizona, dry it out, and sell it in a dry climate.
BTW, I also have a half-inch of standing water in the trunk.
