There are few possibilities that are to be checked to locate the leak. 1) There is a cover under the dash, that goes to evaporator.It has a seal.If this seal is broken, the water will leak. 2) Other possibility is the drain hose on firewall in engine compartment is plugged up or turned upside down. ----------- The drain hose is located on the passengers side on the firewall. The drain tube , It's located on the firewall right behind the transmission dipstick, more towards the center, only sticks out about an inch or so, and is about 3/4" around. You probably can't see it from the bottom of the truck. Shine a light down there, it looks sort of like a shotgun barrel just barely poking through the firewall.---------- The condensate drain at the bottom of the plenum is blocked. It can become blocked from different causes but the fix is the same in most cases. Stick a wire up the drain tube to clear it. You'll probably need to put your car on a lift to see where the drain is.-------
Its hard to see and only sticks out about an inch and is behind a heat shield. It is at the edge of the heat shield so you may have to bend back the heat shield a little to where you can get something down into the drain tube.Once the clogged drain or loose drain tube is cleaned and re-fitted.the leak should stop.
-------------- This should help.Thanks.Helpmech.

Air cond. don't leak onto the ground


If you mean the condensation water from the a/c - the drain tube is probably gunked up.
There is a small tube or hose near the passenger floorboard that the water drains thru. You should be able to see if from under the truck.

I have a 2006 saturn ion 2. Just recently, my ac is draining into the passenger floor board. How do i fix this ?


Bulletin No.: 03-01-39-011B
Date: November 22, 2005
TECHNICAL
Subject:
Water Leaks Into Passenger Compartment Through HVAC Module Condensate Drain Tube When Parked on Incline/Uphill Position (Install Auxiliary Drain Tube Extension)
Models:
2003-2006 Saturn ION Sedans and Coupes
Supercede:
This bulletin is being revised to include the 2005 and 2006 model years. Please discard Corporate Bulletin Number 03-01-39-011A (Section 01 - HVAC).
Condition
When vehicle is parked on an incline with the front end up during a rainstorm or when driving uphill during a rainstorm, water may leak into the passenger compartment through the condensate drain tube opening of the HVAC module.
Cause
Water may drain out of the cowl drain, then drain down the front of the dash panel in the engine compartment and seep into the HVAC module condensate drain tube opening. The water then collects in the heater core cover and upon acceleration may leak into the passenger compartment through the heater core cover seams.
Correction 1. Open the hood and locate the HVAC module condensate drain tube in the engine compartment on the right side of the dash panel.
Important: During installation of the auxiliary drain tube, do not make contact with the HVAC module foam gasket located at the base of the HVAC module condensate drain tube. If the auxiliary drain tube is pushed on too far and makes contact with the foam gasket, water may leak into the passenger compartment.
2. Slide the auxiliary drain tube onto the HVAC module condensate drain tube and make sure that the auxiliary drain tube is angled downwards after installation.cansmo_121.gifcansmo_122.gif

Condensor is leaking into cab. Cannot find the drain tube in the engine compartment to try and clear it... Does anyone know where the drain is located?


  • The condenser won't leak in the cab. Do you mean the heater core? That would leak onto your floorboard if it's leaking. This is located behind the dash. The condenser is full of r134 refrigerant gas. If that's leaking then a discharge of the AC system and a repair would be needed.

  • Hope this helps and thank you for using FixYa.

The driver's side of the floor gets soaking wet when I run the air conditioner. What should I do?


When the air conditioner is running, it forms condensation in the heater box, which is located under the dash board and quite difficult to access. fortunately, you don't have to get in there. The heater box has a drain tube that drains the water out of the front of the fire wall.In the engine compartment,look on the passenger side ,down low on the firewall, for the drain tube. Sometimes it's hard to see, but look closely, its probably covered with the same sound deadening as the rest of the fire wall. You may be able to stick a wire or similar item up into the tube. If not, it will take air pressure from an air blower to blow it out. You'll know when it's free when water starts coming out.

Our 1997 TSI Grand Cherokee air conditioner is leaking in the passenger side. How do we fix it?


You preliminary diagnostic about leak is hafl correct, but this is of a clogged A/C drain hose. It's a very common thing to happen. Here some details:

If your vehicle has an A/C drain hose, it will be located on the engine side of the firewall, below where the two A/C lines go through the firewall.


NO: 24-18-94
GROUP: Heating & A/C
DATE: Nov. 18, 1994
SUBJECT: Condensate Drain Tube Eliminated


MODELS:
1994-1995 (AN) Dakota
1993-1995 (XJ) Cherokee


DISCUSSION: The above vehicles no longer use an air conditioner condensate drain tube. Cherokee's built after September 3, 1993 (MDH 09-03-xx) and Dakota's built after June 1, 1994 (MDH 06-01-xx) no longer need the condensate drain tube. Do not install in the field or submit a shortage and error request.

Somewhere just below the Suction and Liquid Lines you will see a small black hose coming through the firewall and pointing down. This is the A/C drain hose. Take a piece of wire and snake out the hose. This will clear the blockage and allow the water to drain out.

You may have to remove the drain hose completely. If so, it just pulls right out and you can slip it back on easily enough.

The front passenger floor gets sopping wet after I drive and turn off the truck after having had the a/c running. It only does this if I had the a/c running. What's going on? 2003 Dodge Dakota 6 cyl. Aoto...


That sounds like the AC condensation drain tube/hose is plugged up.

The AC evaporator/core condensation drain tube is located on the passenger side of the fire-wall towards the bottom of the fire-wall, (it resembles a heater hose that is coming off from the fire-wall and it connects to nothing, and it is just to drain the AC condensation) and it is easily viewed from under the vehicle. Use long pipe cleaners folded in half to clean out the AC drain, and be very careful that the AC evaporator/core, or the heater core is not damaged from using any hard or sharp objects to clean out the AC drain.

Windows in truck are fogging up


Need more info: I assume you are talking about the side windows, right?
Do they fog up when the truck just sits? Does it make a difference what the outside temp is? Does it small like anti-freeze (sweet smell) in the cab when it happens?

The first and easiest thing to check is drain tube from the air conditioning unit. Air con units are dehumidifiers and the water that they condense from the passenger compartment is supposed to drain out. If the drain gets plugged, then the water sits inside a little reservoir under the dash on the passenger side. From there it goes right back into the cabin raising the humidity and fogging the windows. The drain can be easily cleaned by blowing compressed air up the pipe.

Air conditioning


Look on the outside at the firewall (back end of engine area ) on the passenger side. Little black rubber tube sticking out, usually 90 degrees, pointing down. You need to get something up in there and clean it out, but be careful not to go too far or too hard as you don't want to poke a hole in the unit.
