I had a leak causing the carpet to get wet, I knew it is usually from the HVAC air intake under the plastic cowl cover under the hood. I removed the cowl cover, and sealed up the (hard to see in the photo) crack in the factory seal around the intake peice with some RTV sealer.
There is also a rubber seal on the inside of the cowl cover to keep water from entering the top of intake from the windshield. You can see I circled what was left of the seal and another seal on the side that were both rotted and hard. I replaced the long seal by putting a piece of closed cell foam camper top weatherstrip on the metal where the original seal should have contacted it. Then I made up another seal to replace the little one on the side. I stuck them on and put a bead of RTV on them, to seal to the cowl cover. I did the same to my 98 before and it took care of the leak, I'll see how this one works on my 97.
