Water in the footroom QP

Hello…the first problem of the season. have discovered that water has been collected in the footroom of the passenger side! I had the problem before, but that was due to the plastic cover on the windshield at that time (had been spoiled by the age) water ran pure over inside room filters… however, I immediately replaced this plastic protection and the inner room filter is also dry this time! is there still a weak spot?? where could the water get into the inside room?? hole in the side water flow, which would be funny?!? please help me, water is so gruesome Greetings with 5 cylinds…Ränä
