Condensation Draining in Passenger Floor Area

Help!!! I have a 2005 Liberty. When the AC had been running for a while, water (condensation) starts to leak down the firewall and onto the passenger side floor. Unnoticed, LOTS of water will accumulate, saturating the carpet.

I cleaned the condensation drain, still water inside. I pulled the HVAC unit out of the expecting to find a crack/broken drain tube, cracked lower half of the unit or something. Yet, NO CRACKS! Nothing.

Has anyone run into a problem similar to this?? If so, what did you find and how did you fix?

Thank in advance for your help!!

This info applies to wj grand cherokee models, I don't know if libs are set up the same way, so maybe this helps and maybe not. Can you see the water running outside the firewall and down to the ground like its supposed to when your parked.? If yes, then I suspect it is getting blown back against the firewall when your rolling. The foam gasket there is really just for blocking outside air not water The solution is to extend the drain spout with some hose or tubing, down and away from the firewall.

I have not had this issue with my Liberty, but, My Dodge Caravan did. My 2007 Liberty looks to have the same design. My Liberty has a short piece of hose bent ninety degrees on the A/C drain spigot.

My Caravan has a drain spigot on the firewall so condensation can escape to the outside. My floor was wet inside and the dealer told me the hose was plugged & fixed it for $300. The problem returned so i had to fix it myself. When I ran the engine with A/C on, water would gurgle out the spigot, and there seemed to be such high air pressure in the engine compartment, the water would blow back onto the spigot and run down the firewall. I fixed the problem by buying $20 of misc plumbing parts that I assembled to drain the water into the air that runs under the vehicle. I got a rubber elbow that I slipped on the spigot, an eight inch piece of hose, a pipe fitting with stainless mesh so insects couldn't crawl up, and another length of hose I tie wrapped to the suspension mount. Floor has been dry for several weeks with A/C on and record high humidity.
