The air conditioner drain condensate tube is located under the hood by the heater core . Remove the tube and clean the adapter, it may have picked up road debris.
Assume you're describing the condensate drain tube??? If it becomes plugged with crusted mud or dust that got wet and stuck to the tube, there can be a point that the tube won't drain properly. You may need to get under the vehicle, find the tube and run a small, flexible wire or other object up the tube to allow the condensate to drain. Once you get it open enough to drain, it might be a good idea to run a small tube up the drain and allow a little water, under low pressure to irrigate the drain tube.
Condensate forms on the AC coil as the AC runs for a while. AC units are supposed to have a condensate tube that's designed to drain the water. If the tube is plugged or otherwise damaged the condensate will back up and get into the furnace. To avoid damage you should make sure the condensate is draining properly.
I use a shop vac and reduce the vacuum hose down to fit the drain tube and suck the dirt out.
Under the passenger side carpet at the front of the transmission tunnel.
if it is not obvious.look behind wheelwell cowl.
there is a condensate drain tube in the bottom of the heater core cover/housing that is plugged or maybe the hose is off and doesn't drain outside the car.
The drain tube is on the driver side underneath the car it's really hard to find. if you jack the car up and look just past the headers to your left you'll see a little black tube about a 1/4 of an inch to 1/2 an inch long. hope this helps
There ABSOLUTELY is a drain for the AC evaporator condensate! It is located on the lower firewall on the passenger side. Open the hood, stand by the front wheel (passenger side). You will have to look diagonally down, from above the air cleaner housing. Use a flashlight, as it is dark in that area and the tube is hard to distinguish. You are looking for a short tube, about 2-1/2 inches long and about 1' in diameter. (I have an '02 T&C)
Make sure the water is from the radiator. When an AC is functioning properly, water condenses on the coil and is SUPPOSED to drip down a drain tube below the car. If the tube is blocked the condensate water could be backing up and causing the problems you describe. Check the drain tube when the AC is running. Make sure water is dripping out of the drain tube. If the tube is blocked, run something through to see if you can break the obstruction loose.
What is the problem?
How do i locate the drain to clean it out? Water is on the passanger floor. 2006 Nissan Titan. Thanks
