    1999 Deville (Base) Water Leak(s) Need Help Diagnosing

    Hi guys,

    I have two leaks in question. One has been with me for a while, but its been intermittent. It was coming down the drivers side pillar. I took it to a local window shop and they said they solved it. I saw some of the black silicone residue around some areas and figured it was solved. Parked the car for about a year and now I'm driving it (beginning of rainy season) and it is now coming out of the built black sun visor behind the regular visor. But only when I make a turn. I think usually left.

    Second one is in the trunk, but only on the right and left side. See pic.



    Any ideas? I checked the weatherstripping around the trunk and it looks fine. By fine, I mean no obvious cracks or gaps. Wouldn't budge though.

    leaking coming from sun visor and in trunk.

    If the leak round the windshield keeps migrating it might be solved by removing the window and re sealing it completely. Did the shop do that the last time, or just add more sealant beside the a pillar?

    I think they just dumped some sealant here and there. The is a rust spot center right on the outside bubbling up as if coming up through the roof. It's about half under the weather stripping and half exposed. Kind if hard to describe, I'll see if I can get a pic.
