[Solved] VW Passat B5 - Wet on the rear floor from the passenger side

Hello, I write because I bought a car vw passat b5 version after lifts only there is a problem with it was not raining it was all ok and now it's autumn is back from the passenger side is wet on the floor I really do not know why I checked under the battery if it is clogged and put in wire half a meter into this hole and it seems to me that there is nothing jammed here is everything ok. So I lifted the chair in the back and pulled out the lining in the back and it is really wet but you can not see anything coming out. And the black film in a way how to deal with it and do so I count on the help of professionals.

I suggest to check the outflows from under the glass at the beginning if they are not clogged (left and right)
it is also worth checking the patency of the outflow from the klima condenser
and of course, there is no hole in the floor

You must dismantle the door panels and seal the plate screwed to the door.

It's about the 4 holes that are and I have to check the left and right side and how to check and detach them if necessary. how to check the climate of this condenser where it is located, please picture and detailed description.
And with this floor from the bottom I was looking at it is a built-in plastic housing and it's hard to see because I do not have a channel to check accurately.

Added after 2 [minutes]:

You must dismantle the door panels and seal the plate screwed to the door.

You can ask for more clearly and possibly some pictures

It's about this sheet

I do not know about you, but I at home in the re-house just poured some water in the cistern and knit with some flexible wire until the water orders (only the wire can not be sharp, not to stick anything, but hard enough to penetrate any dirt) me these runoffs are rubber do not know how it looks in the passat
the outflow from the fan is either on the wall behind the engine in the bottom part or in the floor
enter in google "passat b5 klimy outflow" and it will definitely pop out

Thanks tomorrow I will look after work and I will write what and how

After removing the sides, you should notice a water leak between the sheet and the door.

I had a similar problem, but under the lining was about a centimeter of water. The water got a damaged gasket on the base of the cabin filter. I replaced the entire base because, unfortunately, the gasket itself does not exist ..

As above ..... check if the battery does not float ....

I had similarly - in truth, in the citroen but ... Check if you do not have a wet liner in the trunk.U mint water was getting into the trunk, the car was often leaning forward and the water from the trunk was dripping on the rear rugs, Wet dry on the back wet .
