I haven't replaced the windshield.
It's the driver's side.
A/C box drains.
Cowl drains.
No sunroof.
I pulled the carpet back some. dried the puddles with a towel. The insulation under the carpet is...unfortunate. I pushed it up as much as I could. I recon the shell unibody comes down the line at the factory and that underlayment goes down first. It has pass-thru holes in it for various things.
I pulled the wiper arms and got the cowl cover off. I laid a water hose in it and went inside to look. I saw water trickling , but I'm not sure it wasn't wringing out of the underlayment as I folded it and pushed it up to get a better look.
I looked inside the cowl. I saw where that seam-sealer putty, at the very far right, and almost not visible, didn't bridge between what might be the sheets of a welded pinch seam. Couldn't tell, but don't see why the putty would be there unless there's a seam. The putty dries like hard plastic but I could poke my finger under it. I bought some sealant at Autozone and very liberally applied it. It was one of those situations where you could see the gap to be sealed until you put your hand in the only way it could go. Spread it by feel with my finger.
If cussin' fixes leaks I expect success.
