Kick panel leaking

I've read all the threads related to this but I cant seem to find a clear answer or solution that has worked for me.

I'm getting water coming in somewhere behind my kick panels when it rains (seal/bolt holes, something else). I have removed cowl and sealed it with seam sealer. I have removed ALL debris from the plenum. Problem is when I remove the kick panel its hard to pinpoint where its coming in. By the looks of it the seals are shot (they are foam), which I plan on replacing. Is this seal something that would stop water because it looks like more of an air seal?

I guess I'm asking if anyone has fixed their problem by replacing those seals and if anyone has any other experiences where it could be leaking from. (No its not windshield - i tested by placing hose in the cowl only.)

All of the cowl water will go by that inlet so yes that's probably your water source

I have done everything and mine still leak. Bout ready to sell at this point.

the cowl drains exit behind the front fenders. watch where water comes out when you dump a hose into the cowl. there is a plastic trim piece to remove, if still present, and a little piece of permeable foam to pull out of the way. then you have to reach up with a stick or something and pull out what you can. then flush water down. then pull out what you can. and repeat that process until nothing else comes down on both sides. it is a wet and dirty job to do this. then push the foam piece back and reinstall the plastic trim piece. sealing up everything to keep water out just masks the problem that debris is holding water in there.
