I bought my 4Runner in November and as far as I know it's the original windshield. My driver's side floor has been wet all winter. I just figured it was from the holes in the floor mat but I sealed those and it's been dry lately yet the carpet would be wet. I pulled up the carpet and the insulation pad was SOAKED! I wrung it out and water was pouring out of it. Anyway, I pulled the weather stripping back and my A pillar doesn't seem to have the same holes in it like the other guys who posted in this thread.
Can someone who's been through this give me some guidance on what I should do to correct the leak? tHere are some pics that I took with everything apart.
Floor
Not really pleased about the surface rust. It must have been wet for a long time under there -
A-pillar
These aren't holes, rather just notches. I filled them with sealant anyway.
Cowl. The rubber edging was coming off of the cowl so I snapped it back on.
