AC condensation in passenger floor

[BentGear]

I final got the AC working. It is blowing good and cold, however now there is a lot condensation puddling in the passenger floor board. Is there a drain hose or something I should be looking for that is missing?  

 

I am not 100% sure where is coming from but I think it's just condensation from a hot and humid Georgia summer. 

 

Glad to have AC though!

Got it fixed. The hose coming out the firewall was crimped.

The tip of the train hose is supposed to be pinched closed, in an effort to stop road grime, dust, etc., from getting up in there and plugging it up, while still allowing for condensation to get pushed out by the gentle pressure from the fan. A bit like the outlet on a whoopee cushion but without the extra flap length for sound production. 

Problem is the hvac on an old vehicle doesn’t have any sort of filtration so it will eventually plug with dust from inside.
 

For the benefit of future readers, the a/c drain tube is on the passenger side firewall in the engine bay right above the frame rail, if you forgive my terrible phone art:

Directly below the charcoal canister on my ‘91, I don’t know that the canister is in the same location on a Renix but the location relative to the blower motor that you can see on the left is the same. It comes straight out and does a 90° bend downwards. 

And this is the pointy pinched shut tip, next to starter on a 4.0:

 

Generally speaking giving the tip a squeeze should be enough to pop the tip open and let the accumulated water blow out the plug, but it might be necessary to push something into the end to bust it up. The hose also pops off the firewall easily enough for a very thorough cleaning. 

Also worth warning, if you’ve got enough condensation in there it’s coming out the floor vents you’ll get a couple gallons of water out of it when you blow it free. On the off chance you’re somewhere you wouldn’t want to dump that much water on the ground.
