I was afraid you’d say that haha. That’s the chapter of the two at least.

Sorry to resurrect the old thread, but i need help.

The first few pics here are gone, and im trying to fix my evap hose issue. I just replaced my compressor to make ac work, and it works, but the water condensate drips in the foot well (from the big black box). So i assume its an issue with the drain, but i cant find where the drain is supposed to be... can i get to it without taking things apart? The system itself looks like a fresh restoration.

The evaporator/condenser whatever you want to call it screws onto a drain pan which has two tubes that poke through the box and through the firewall.



You can see the tubes poking out the bottom of the box, they also should just be poking out from the firewall in the engine bay.

Ok, i think i saw those two, except they are not that color, they look bronze and i see them in engine bay... so why am i leaking inside? Both footwells (more so on passenger side).

Is there a way to remove the pan without taking everything apart? I cant really see the pan, i only see the black box under there (where the foot wents are and where the moisture forms..).

Is it coolant or condensation?

If condensation it could only be if the drain tubes are blocked or condensation is forming elsewhere in the box. I'd give them a poke with something incase bugs have turned them into a home.

The temperature valve, mounts w three unusual screws on the firewall from the engine compartment; or the internal valve or connectors could be leaking coolant.  Anti-freeze smell would be the giveaway.

Def water. The whole system seems brand new, but was done before i got the car.

I can see condensation forming on the box.

I will try to poke the tubes.

Hii!

So its summer again, and it means that i have recharged my ac system and... its leaking again.
Was leaking water primarily on the passenger side, would leak water on the drivers side after extended use (an hour).


So i took cloth hanger, and compressed air and went at it. The passenger side started working, yay! The water is dripping out of the tube... the drivers side, however, came back with a vengeance!! After a few minutes of ac system operating, it starts to pour inside the car out of the vents (at the bottom).

1. Does the tube bend in any way? I can only push the cloth hanger straight. It doesnt bend to go anywhere.

2. Any ideas what to do next? Is there an easy way to remove the train to investigate? The tube that goes outside sits tight, i cant move it. The whole system looks brand new (car has 2k miles after restoration).

3. Can i just spray some silicone inside the tube, to block off that end, so that all the water goes out the passenger side tube? (Why is there two tubes anyway...).

4. Does anyone have pictures additional pictures of the tray and under the ac system? Everything is closed off on mine, and without taking things apart, i cant see anything. The two pics above are great, but i cant see inside the tray or how it connects to the rest of the system.

The only way to fix it is pull the box out & take it apart, it will come out with the dash in place.

Any way to just pull out the tray, without pulling out the whole system?
What could be broken there?? If i were to guess, the tube is somehow not attached, but i cant find pictures of where it attaches and how.

Does the tube inside the tray go straight back? Or does it kink up? How is the tube attached to the tray?
