    Airco leaks water in interior

    My airco leaks its condensing water into the interior ☹️ Does anyone know what to do.
    I also see water under the car, but most gets oout of the black airco unit under the dashboard. I have the idea that the seal between the unit and the central part of the hearing system is leaking. Does that sound familiar to someone?

    Many thanks from a dutch guy with wet feet

    Sounds like your evaporator may not be draining properly. See if these threads might be of some help to you:

    Known problem.

    It's the evaporator draining fresh (condensed) A/C water into the cabin instead of into the drain tube.

    The condensate drain tube/elbow is clogged or something is blocking the outlet from the housing into the drain tube.

    Additional to the linked threads above there is this thread pointing to a method of making a good connection of the tube to the evaporator box:

    This is important to know about because it may be difficult for you to reattach the drain OE tube and elbow to the box after removal and cleaning.

    As probably seen in these threads - depending on where the water flow is blocked, be prepared for a lot of water to come out of the box when you remove the drain tube from the evaporator box.

    Dutch guy with wet feet! I like this joke.
    May your D soon be dry inside.

    Thanks! I indeed had a clogged drain. I got access to it through the fuel access area and after blowing into the tube i heard that there was a lot of water inside the evaporator and it was coming out directly! Hopefully this has solved the issue, but i'm afraid more dirt will be inside of it. I will closely monitor it.
    Next challenge is getting the foam carpets dry.... Not that easy in the Netherlands

    Mine condenses and drips from the evap tubes where they come into the car by the pass Side foot well. I guess i should wrap them in pipe insulation.

    Hervey shows "Cork Tape" for that job on this page:

    Anybody have a pointer on it or can point to a thread on this?

    It's not all that difficult to remove the carpet, take out the seat (4 nuts under the car) and the carpet lifts out.
