Cowl/water dam replacement help
I'm sick of opening my door to 2 inches of water everytime it rains so I want to get this out of the way, it's like the last panel that's rotted on my car. I was planning on replacing the top middle section that has the windshield wiper motor in it and where the water runs down to the fenders. Any guides on this? Do I have to remove the front section of the firewall or does it slide behind that? Any pictures of it?. Tac weld spots?

it's the under the screens, the wiper motor arms are in the valley, the rain water runs down the sides and down the fender.

If the base of the windshield is rusted through the water will run into the driver's compartment. I had already patched the area below the dash metal in this pic but if yours was Swiss cheese like mine was then water can run right in behind the dash. The area inside the cowl where the wiper transmission is mounted doesn't usually have a lot of rust. Usually they rust at the bottom on each side of the cowl. You also have to make sure the cowl can drain at each side. If there's crap in there plugging it up the water can make it's way into the cabin too
The lower cowl has to drain into the rocker panels. If the rocker panel drains are plugged up that can force water into the cabin as well. You can see how the lower cowl was rusted out in this pic. It's from crap building up in the lower cowl, retaining moisture and then rusting. The outside of mine was rusted as well
