Re: Cowl leaks

My suburban does the same thing. It is rotted under the dash right where the fresh air boxes are spotted to the upper cowl.

I plan on drilling out spots, and removing them for repair.

Re: Cowl leaks

Mine leaks from the spot welded seam in the bottom of the cowl, in front of the glovebox. I assume there was some seam sealer between the two panels originally. This picture I stole shows the seam.

Re: Cowl leaks

Mike... note that the rain gutter above the windshield if it leaks, it will run to the windshield post and down either to the side panel or agaisnt the inside of the firewall. I had that issue.

The one under the dash might be coming from where the wiper motor mounts to the inside of the cab.

The seal on mine isn't the best and I get a few drops inside in a heavy rain. I haven't looked into it full scale yet, but after a brief look, I think that's the culprit in my case. That might be the case for your under dash leak.
