Locate AC drain line

Sounds like you have found your problem, on the fire wall down low on the passenger side there should be your drain most are a elbow rubber type hose check it and I believe you have your solved. Good Luck Mike

You need to find the drain pan line that comes through the firewall. Open the hood and search for the line on the passenger side firewall. The line is probably clogged from insects, animals, or other gunk. use a short piece of dowel or wire to unclog the line and allow the pan to drain to the outside of the vehicle.

Could it be the exaust pipe? I would say if its only water dont worry about it.

The condensate drain hole or pipe must be blocked. This drains the water to outside the car.

there is a a/c drain mounted in the firewall that is plugged up. you will need to clean this drain out

AC outlet pipe is blocked ,their is a drain pipe for the AC unit under the passenger side dash and you should find a drain pipe that runs through the firewall ,

The easiest way, to me anyway, was to locate the drain on the passenger side firewall on the bottom of the vehicle and to use a hanger or other sturdy wire to push and dig the debris out.

Just had ours fixed, look on engine side of firewall, if the outlet pipe in passenger well is a 3/4 inch long pipe projecting forward into engine bay with no tubing leading down towards the ground, the problem is water comes out trickles back with pressure in engine bay to foam seal under the pipe and enters footwell inside car.
Take a piece of rubber tubing and hose clamp it on and direct it down towards ground in engine bay and the problem will be solved!
We have gone from soaking carpet to no leak at all with this simple fix.

The outlet drain hose/pipe from the Internal air intake, to the outside world, is plugged up. Locate it and rake out the deris, then Happiness.

Rather than pay the dealer $350+ to fix this, I found the "L" shaped drain hose behind and interior to the front passenger tire (I let the car idle with the AC on and waited for a drip. On my back on groud I reached in and found the drain line and it came off i my hand and about 4 oz of water and some decayed matter floowed out. I reaced back in and found the hole to which the L line was attached. It was a rubber fitting on the end of a metal pipe. The fitting came off easily and then about 8 oz of water flowed out (carpet had been soaked for two days). I reattached the L drain line and noticed that inside the fitting was about 1/4 tsp of "mulch" - decayed leaves, pollen, etc. Reattacted the fitting and water now flows freely out the drain. And yes, its a very high humidity area - Houston, TX. And if you live anywhere near here you know about the intense yearly dispersion of Pine tree pollen. I thisnk that accelerates the blockage. Happen about every 2 years. (Third time for me. First two I let the dealer over charge me for this effort. BE SAFE WORKING UNDER YOUR CAR!
