    Evaporator Drain Clogged

    Noticed a little bit of water in the floorboard on the Z8 after driving it on a humid day. The car pretty much never gets driven in the rain and it had been a while since it was washed. I took it to my buddy’s place who is a BMW master tech and we looked it over blew out some drains underneath and let it idle with the a/c cranked up and set the climate control to let in outside air. The car had a huge puddle of water outside underneath and none inside the cabin, so we called it good and I drove home. On the way home I switched it to recirculate and immediately noticed some water in the passenger floorboard area. Has anyone encountered an issue like this?

    Yes, this is a known and discussed issue, by memory there's an AC drainage tube that gets cogged.

    Thanks for the response. Any idea what I need to disassemble to clear it?
