    2012 SR5 4Runner
    This is my 1st post on this forum, so bare with me please. I have a 2012 SR5 that I purchased new. Last week I drove about 5 hours with the AC on. When I got home, I noticed that the driver side REAR carpet was soaked with water. The driver side FRONT was just a little damp. After hours of drying the carpet (with fans and shop vac), I thought the problem was the sunroof leaking. As it turns out there are 2 flat vents (see pic) under both front seats that blow hot or AC air to the back of the 4runner. With AC on, in my case, the vents under the driver seat literally blow water out! ! With the shop vac, I sucked at least a quart+ of water out of these vents. The rubber AC condensate drain under the hood on the passenger side appears to be draining properly. I pushed a length of heavy nylon weed-wacker line in about a foot. Also blew compressed air into drainage tube. I see no change; still blow water from vents.IMG_2434.jpg
    Is there possibly another drainage tube for the rear vents?
    I'm at a loss as what to do next. Suggestions and ideas welcomed.

    We had a suburban that spit ice out of the vents due to high humidity freezing on the coils and blowing out. I had a jeep that did the same thing. Do you live in a high humidity area?

    Riem00, thx for the response. Yes, i was driving in high temp and high humidity...AC was on max. I hope this is the problem (don't want a costly fix). I now have the carpet dried out and have fabricated a temporary "water catch" tray to fit under the two vents. Hopefully, this will prevent a future carpet soaking. What puzzles me is that I have not noticed this before. I've had this 4runner since new (bought 12/2012 as I recall).
