2001 jeep grand cherokee
Hi. The basics: new member, 56 yr old female who is a diy'er because I can't afford to pay somebody to do it for me. Problem: water in the passenger floor. I've read enough to know it's probably the ac drain. I've located it and tried to use my air compressor to blow any trash out. Nothing. I tried to push a flexible wire into the drain and it felt like it was blocked with something hard. I had to remove the passenger seat and pulled up the carpet and used my shop vac to get the water out, but need help to repair the problem. Please advise. Many thanks.

I had this issue once with my truck and it ended up being a crack in the plastic tray that holds the water from the evaporator. I let it dry for a few days and siliconed it.

Old fart with a wrench
OR the seal at the firewall is leaking.

Problem #1 was the foam gasket around the drain tube was pretty much gone. Why anyone would use a foam gasket in a liquid application I will never understand. Crawled underneath and located the tube on the exterior of the firewall just above the starter. The gasket was pushed through so I was able to remove it. I used plumbers putty to repack the hole around the tube. I did this on both sides of the firewall. I then used Permatex Ultra Grey to seal it up. Then I drilled a 3/8 hole in the back of the drain (the round black plastic piece on the interior side) and blew air through to ensure the tube was open.
Problem #2 is that the drain tube is too short and too level on the exterior. Unless you drive downhill all the time it can't possibly drain properly. Water dribbles out the tube and then flows right back along the bottom of the tube back to the firewall and through the foam gasket into the floorboard. I went to O'Reillys and picked up some 5/8 heater hose and a hose clamp. Threaded the hose up at the front of the starter and pushed it onto the tube. It was a little snug but some Dawn on the inside of the hose let it slip right on. Fastened it with the hose clamp and turned the tube to look straight down and zip-tied it to the frame rail. Now the water has no choice but to run down and hit the ground. I then plugged the hole I drilled with a 3/8 threaded plug coated with Permatex.
Like I said, I just did this today but I am fully confident it will solve the issue permanently. And as a bonus, the tube is now easily accesible to rod out should it ever become clogged. Hope this helps.
