    Does anyone know where the drain for CLK side windows drains to? (see pic)

    Right now some of water from that drain seems to exit via holes in the bottom of the sill, but most of the water finds it way under the o/s/r passenger footwell - the carpet is soaked after rain.

    It looks like a drain tube or something is blocked or disconnected.

    Can anyone give any pointers here?

    Many thanks,

    Dave.

    Haven't driven the car for a couple of days, got in it today to find the drivers footwell now swimming in water.

    Checked all the windscreen drains very recently and all seem clear (water runs away no problem). Can't find where all this water is coming from.

    Any suggestions what to check next?

    Remove the plastic shield in front of the windscreen,on the passenger side you will see a
    water trap,unblock the drain at the bottom,do it asap.

    I didn't realise that thing needed to come off and drains are behind it too.

    Funny thing is water is drivers side, but will do it asap anyway. Its bad, its a lot of water. Now got electrical weirdness with warning lights randomly showing momentarily.

    Thanks very much for the advice.

    Solved. The drain under the fusebox was completely blocked. Water coming in from the bonnet vents backed up due to the blocked drain and had no-where to go but make it's way into the the drivers footwell before running through to the rear passenger footwell (nothing to do with the side window drains at all)

    The drain under the fuse box can be accessed by removing the o/s wheel arch liner (see pic). The drain was totally blocked as in the pic.

    This caused not only wet carpets but interfered with electrics too, with weird warning lights and messages showing intermittently. Luckily this has stopped, so no permanent damage.

    Also noticed a large grommet in the bulkhead behind the wheel arch liner had perished badly, letting in water too. It was also a good chance to clear all the mud, silt and leave debris which had built up behind the wing.

    Now I need to dry the carpets and sound deadening. How difficult is it to get them out?
