Leaking under passenger side dash after A/C fix

[bezjeep]

Trying to figure out why I'm getting water on the passenger side floor board. I thought it could be a leak from the cowl section but it has rained in a little while and I just put the hose on it to see. Not much different. When I push on the plastic seen in pictures, more water will come out.  I don't even know what that thing is. Any insight? Thanks.

There is an AC vent hose that goes through the firewall. If it’s missing the rubber downspout it will leak back into the cab.

 Oh ok thank you. So I check this via the engine bay against the firewall?

Looks like the rubber elbow is connected but I do see plenty of moisture and can even see it in the fender well area seeping.

Wrong elbow, look near your charcoal canister

Here is a link to the replacement drain hose incase yours is missing: https://teamcherokee.com/a-c-drain-hose-oem-cherokee-1984-1999/

Most of the time the tip of the hose facing down is stuck closed.

I think I used 3/4" heater hose from the parts store. Slid right on but not loose, hasn't budged in over a year. @$2/ft at the parts stores

The replacement tube is only $3.25 and is properly molded already to fit around the frame rail and the ac housing

Looks like my problem was a clogged tube

I knew it....LOL. Usually all a guy has to do is pinch the snake's mouth from each side and keep his face out of the way. All sorts of crap comes out.

How would you clean the "nub" coming out of the firewall? There's a lot of junk in there. I'm guessing coat hangar? 

[cruiser54]

Or just pull it off and clean it.

I got the rubber hose cleaned and it's in good shape. I'm talking about the 1" plastic nub coming out. Can I detach from the inside? I'm thinking shopvac might work

[cruiser54]

It doesn't detach.

Cruiser is correct.  You might be able to snake a small piece of coat-hanger wire into the nipple on the heater box and loosen any crap that is plugging it up.   Then maybe a vacuum with a crevice tool might be able to suck the stuff out the hole.

 

The next level of attack to clean out the drain hole is a huge pain.....remove the heater box, disassemble, clean, reassemble, and reinstall.
