Air conditioner leaks on carpet 2000 jeep grand cheroke. have already cleaned out the tube that goes through firewall, seems to have good flow. took to shop, they verified tube appears unobstructed, and only leaks after time, not right away. definitely not a body or door seal leak. pulled carpet back, source is from plastic housing area just inside cabin at firewall penetration, where there is a foam/sponge like gasket. ?could this be condensation on the outside of the drain tube occuring inside the cabin area? our 1997 jeep has exact same problem, except can not verify tube not obstructed. thank you in advance

My wife's 2004 Jeep Grand Cherokee has had the same problem what I did was take the air intake tube off and cleaned the carbon build up around the air intake valve. I used carbrator spray and a soft cloth to clean this build up off. Make sure to change your air filter and clean out any debris in the air filter box and other air intake tube. If this doesn't help check the Jeep website for information about some electrical module that when it's bad can causes this problem.
Do you have a sunroof?you might need to clean drain tubes.have you had a windshield replaced?or it could be a body seem.you will need to remove panels and lift up corner of the carpet and run the garden hose over the area and check for water in vehicle.
The water is probably coming from the air conditioner. There is a drain tube that is supposed to let the water condenstion get out of the system, but the tube sometimes gets plugged. Look on the engine side of the firewall, usually below where the a/c lines go in for a tube coming out of the firewall that is not connected to anything. Make sure that tube is clear.
The air conditioner condensation drain is under the hood not inside the car. The fluid is probably a leaking heater coil. It is located on the passenger side firewall.
That is the area the air conditioner vent drains. There aren't a lot of fluids possible - coolant, power steering fluid and transmission fluid are the only ones that would be in that position unless your windshield washer fluid leaks from the tubing. Brake fluid would be closer to the wheels. If the air conditioner runs at all it removes moisture from the passenger compartment and drains near the passenger side firewall. All the other fluids would hae a definite smell.
You AC drain is blocked with foreign mater, leak is worse when AC is used, pull back the carpet and run water down the cowl opening with a garden hose, slow flow, and check to see if the hvac housings is not cracked, or sealed to firewall. GOOD LUCK. RDJRP
The a/c drain tube will be located on the firewall. It will be on the passenger side twards the bottom of the firewall. It will be about 3/8 inch in diameter, and about 1-2 inches long sticking out of the firewall. You will probably need to get under the vehicle to gain acess.
I have a 2006 Fusion with the same issue and I fixed it for less than $2. There is a drain tube that goes from the passenger floor board out through the firewall to allow water to drain under the vehicle. However, water can travel along the underside and seep back into the vehicle. I went to a hardware store and bought a few inches of 5/8" tubing. I simply slipped this onto the drain and the water now flows down the tube and safely away from the interior of the car. Been dry ever since.
