Ok, so I found a small lake on the passenger side of my TJ (1999, 2.5L, the rest of the info doesn't matter...) yesterday. Assumed it had something to do with the rain. Pulled the carpets, and left them out to dry. Drove up to the lake today (no rain) and managed to develop another small lake in my TJ. Definitely not a rain issue... turns out it is the A/C.
Found some stuff online -- part of it makes sense. There's a drain tube for the AC. Runs from inside to outside. Problem is, the outside part is barely outside and allows the water to run back in. Fix: $2 worth of hose and a clamp. In theory...
Bought the hose and clamp, but noticed something when I got home. Just sitting there, I could watch the water run from the firewall to the floorboard. I know exactly where the leak is, but can't get to it. Seems like the area under the dash is all one big piece, and the plastic goes right up to the firewall. Actually, there's a piece of foam between the plastic and the firewall, and that's where the water is dripping. What makes things worse is I have an aftermarket A/C system -- don't know if there's going to be any differences from the stock setup. I've had it for two years without leaking issues. Thoughts?
Thanks!
