I discovered a few months back that I was having a problem with the passenger side floorboard of my truck being wet. Upon inspection, it was quite wet, and I took the truck off the road 2 weeks ago to tear out the interior to locate the source, remedy it and then install an upgraded sound system. I finished tearing out the interior this weekend, and had removed the jute and carpet to dry last weekend.
I noticed at that time, the water was running back the under the door sills, and had soaked the rear passenger side area as well. So today, with nothing in the truck, I pulled it out of the garage, started, and cranked the A/C on high for about 15 minutes. Sometime between the 10-15 minute mark, I noticed water pooling up on the passenger side. I had read that perhaps the drain was plugged, and would need cleared. That is when I discovered that I had no drain tube. Nor did I have the plastic elbow that protrudes from the fire wall that the drain tube attaches to. Not sure how or where it got lost, I would guess perhaps something happened to it along the way with the up pipe swaps. We ran a coat hanger through the opening(hoping something would dislodge to indicate a blockage, no such luck.
So, my question is, will simply replacing the elbow/hose remedy the water leak? Or is this going to turn into an issue with trying to remove the heater core (black box inside truck under dash that seems to drain trough firewall into where the elbow should be). I'm not sure if the elbow just snaps into place through the firewall hole, or if it was part of the heater core and got broken off and now I'm F'd? I'd really like the water to run out of the cab, and be able to start putting my truck back together.
Sorry for the long winded post.

The vent is plugged for the evaporater, there is a rubber elbow that sticks out of the firewall beneath the accumulater on the pass side. Take it out and clean it. the water should drain out of vent by the firewall and not pool up in the interior

I have the same wet carpet spot issue exactly. And i happen to have all my interior out:D However, i havent looked into it yet. I thought i had a leak from the windshield or cowl cause mine IIRC got wet after a wash or rain? Cant remember. Need to figure it out before it goes back togather. Wet carpet stinks:spit:

There is a cleaner that you can feed the hose inside were the elbo was and it will foam up and clean the area out if cloged up. also alittle air would not hurt.

Ok,
1 fundamental question, since I am missing the elbow and hose, can those be installed relatively easily? Does perhaps the elbow just twist and lock into place? Or is something actually broken off that will prevent this? We put a coat hanger in there, and it seemed to hit nothing to indicate a plug, but I will exhaust all efforts before I call it good and put it back together. Henry, do you have any diagrams of the heatercore and drain?
Thanks.

Thanks Henry, but I am still trying to ascertain what to do if you are missing your A/C evaporator drain tube. How does that attach through the fire wall? Do you have access to a diagram of how it goes together?

Ted I got tired looking this morning for it. There should be a nub sticking out and you slip that elbo on there.

That's just it, no nub, no nothing. That tells me it may have been broken off.
:mad:

It comes through the firewall about 2" directly below the evaporator (insulated canister on the firewall behind the fuel filter) on the firewall, a short 90 degree elbow with a short piece of hose for draining, and there is nothing there. If you reach down and feel around, you can locate the hole through the firewall and firewall insulation where it should be, but the elbow/nub is gone.
