Water coming from under passenger dash
What could be causing this?
2014 VW Touareg V6.
I took to the shop a month ago thinking it was a clogged AC condensate drain line. They said they blew it out. A few days later and water poured out again. I took it to the shop again and they said the line was clear and they didn’t know what was causing the water and couldn’t replicate it. I drove around a few weeks with the panel off to watch for more water. After several storms nothing dripped down. Now yesterday a bunch of water flowed out after 30 minutes of a drive. Weather was 95F out so AC was running. The last pic is me under the hood peeking under the plastic cover of the windshield wiper. I had seen a video that there’s a reservoir on that side that might get backed up. Could that be it?
Edit add make and model
