I found water under door trim soaking front carpet coming from the roof rack, through left side support column, and down past the fuse panel. I isolated it by carefully pouring water into the fore/aft roof strut and letting it accumulate at the forward end. Good Luck and Cheers. Wavelength.

 

What a head scratcher, right? Well........I found it. After the "dealer" said, "it ain't clogged drains, its the windshield seal". I had a fella all set to swap it out, then he said..."I'm just gonna check one thing first BEFORE I swap a windshield". He blasted with the water hose until I saw water coming in. Then he found this after visually inspecting where the water was coming from. A freakin HOLE right above the front blower motor. You can even see the hanging duct tape where someone attempted a patch.

 

Water shouldn't be collecting there anyway. You have a leak but It's not going to be the windshield. Two places they leak. The inside door seal that slips around the pinch went around the door opening tends to leak. Quick and easy fix it to pull it off and squeeze the u-channel together so it's tight again and reinstall. There's a u-shaped piece of metal inside and it fatigues over time and gets bent by people drabbing it while getting in and out.

The second place is under the cowl cover on the passenger side. Remove the wipers and remove the cowl cover. There will be a body color rectangular cover that's supposed to be permanently glued over an opening above the hvac box. The seal breaks and the cover separated from the cowl. I carefully removed mine then using a generous amount of sealant (RTV works well) I apply the sealant around the edge then install the cover then tape it down while the sealant cures. Once cured, remove the tape, reinstall the cowl cover and reinstall the wipers.
