Chevrolet Repair: leak in drivers side, hard rain, mastic

Question
i own a 97 s10 4*4 and its always real wet on the drivers side. where is this water coming from after a hard rain, theres no visable rust or anything from underneath, but i think the water gets trapped between the body somewheres.

Hello John,
I have seen this problem discussed in a forum I read a lot. I will send the link, so you can look through the posts. The forum is free...and very informative.

Seems the rain goes down through that grille under the windshield, between the windshield and hood, and leaks through a seam in the body sheet metal. The fix is to remove that grille, and get in there with some mastic.
