Found this while googling "ac leaking on feet in patriot" ...
My 2008 patriot had the same odd swooshing sound in the dash, only when I started using the ac. Me and my wife's toes were getting wet too and I was worried I would have to spend lots of money to take it to the dealer. I just followed the directions in this thread and bada-bing-bada-boom, fixed !!!
I gotta say, the pictures really made the difference. I hope we can all post pics in the descriptions like that so everyone really understands where the parts are located and what to avoid.
PS. I had a bunch of junk in the hose too, and when I was cleaning it in the sink, (just stuck an unsharpened pencil in half way one end at a time while straigtening the hose) some big ol' insect wings fell out followed by some muddy looking substance. I think what happens is all that time during the year when not using the ac and cycling water through the hose, bugs get stuck inside and the dirt somehow starts to collect around it. This leads me to believe that I might be having to clean out this hose once a year to prepare for those hot hot summers !
Also, yeah that was a heck of a lot of water that came out, def over a gallon, I filled up a whole large plastic salad bowl (use what you can). I couldn't find a water hose to divert the water away so the bowl was just fine. Also I don't think there's enough time to switch the two hoses to divert the water cause once you pull that ac drain hose off, it starts flowing pretty dang fast ! Do what I did, pull that hard carpet far out from under the gas pedal and from the corner as much as you can without totally bending the heck out of it, then pull the hose from the floor end out of the floor hole. Then scoop that large large plastic salad bowl or clean oil pan or whatever you got underneath the pedal and just under the nozzle that the drain hose connects to. If you do it right, the side of the bowl will fit snug right around the drain nozzle to keep all the water into the bowl. Make sure that the floor end of the hose is sitting in the bowl then pull the little drain hose out of the top end, might need a little twisting action, and let the water drain into the bowl...
I bet I just saved a ton of money. Very rewarding feeling ! Thanks guys for this awesome thread !
