Water leak / air conditioning?

[gon2srf [OP]]

I have water running down into the passenger side compartment and the water is pooling under the plastic floorboard. There are two air conditioning lines that you can see from the engine compartment that run through the firewall and into the passenger compartment air/fan unit. I'm thinking that one of the lines is cracked or possiblly the fan unit is cracked? Is water stored anywhere in the unit or is it more likely the AC line?

Anyone else experience anything like this?

Also the drain line could be stopped or plugged up.

i think you should try dominics onboard dehumidifier mod

Thanks, I'll check that out.

+1

Water condenses out of the air on the A/C condenser and it is supposed to drain out the bottom of the truck on the passenger side. Your drain must be plugged.

I had an extremely leaky roof.. with water leaking out from underneath the dash. It was bad. CLICK

Ok, I just spent a half hour trying to track down the discharge line to no avail. To me the system looks closed but that is just my initial assessment. Any pros here that can point me to the appropriate location of the discharge line? I am assuming since it is called a discharge line, then it carries the outbound fluids for discharge overboard?

The discharge line is #11 in the illustration.

I'll take a shot at this one. The drain should be coming out of the evaporator enclosure. The evaporator is the radiator type thing inside the passenger compartment. It's what gets cold and cools the air moving over it. When the air is cooled, water condenses on the outside of the evaporator coils, fins or whatever. This water drips to the bottom of the enclosure and exits through a drain port which should have a hose connected to it that discharges beneath the vehicle on the passenger side. I think the #11 line in the diagram may be a refrigerant line and not a drain line. There should be another diagram showing the evaporator and associated lines.

Once you locate the drain line you might try blowing some air back through it to clear out any blockage. It could be something like a glob of lint maybe. A shop vac might also work either blowing back or with suction. I would like to know for sure that whatever was causing the blockage has been removed. You should be able to crawl under the passenger side and spot the drain line. It will likely just be an open ended rubber tube. Be gentle if you poke anything through that tube to clear it. You don't want to punch a hole in the evaporator or the enclosure. Unlikely, but be careful anyway.

Thanks very much. Below is the illustration of the evaporator assembly. #10 is the servo drain hose? I did a lot of crawling and didn't spot the hose.
