Model: C300 2011 W204 - Sport Edition

Issue: Water leak by foot rest of driver side. Leak is falling on left foot rest.

Request: Use video as reference to identify component(s) that could be causing drip. (video is just under 2 minutes long)

Educated guess: Either worn out element of cowl vent or wiper blade mechanism. I say this based on the key part of the video were drops are forming where it is not expected. I don't have the name for the object the water drops are landing on inside the hood.

If anyone can help me isolate the components I could do some shopping to mend the issue. Thank you in advance to anyone who takes the time see the clip.

Update

1. I shared the same video to a mechanic friend. He happen to have another W204 in the shop. He popped the hood, took a hose and poured water the same way I did. The result was interesting. Water certainly flowed from the cowl vent down the drain pipe - but - it did not drip onto the black object below it like it does on my video.
2. We checked the other usual suspects including sunroof vent, pillars, passenger side vents, etc. NTF.

We think there must be a crack in the windshield cowl vent. Im going to order that on eBay, install it and see if it fix's the drip.

I had a similar issue with my cowl. It separated from the windshield towards the middle and allowed water to seep down through the firewall onto my drivers floor. I fixed it by sealing the cowl and the windshield with some silicone sealant. Havent had the issue since
