Question about 2000 Nissan Altima

Open Question

Water from AC leaking into front passenger floorboard. I have had to get the drain tube ? cleaned out before because of this same this something I could get to and do myself? Someone told me that it could also be because I don't have enough freon ,and the unit is freezing up,then leaking into the car. Please advise. Don't want to spend too much money on something I could problem solve myself. thanks

    You should be able to see the drain tube from under the car. Try sticking a coat hanger in to see if you can open it up.

SOURCE: The anit-freez is leaking from the front passengre side.

that sounds definately like a water pump,without a doubt.
---Rinse all the coolant off the engine and radiator. After letting everything dry thoroughly, start the engine with the hood up, and watch for leaks. With this much coolant leaking you should easily find the leak. 

Could be a heater hose, or lower rad. hose. If not I would dye test it. Autozone has a loaner kit. Contains fluro dye and a blacklight. Makes it very easy to track it to the source. 

---------------------- a person having a same problem like your solved the problem .and what it was is as follows ------ I have a 96 DeVille and it had the same problem. What turned out to be wrong was that my car has 2 fans, 1 should come on when start the car and the second comes on when the engine is under a heavy load (ex. stop & go traffic, a/c running on a very hot day). My primary fan wasn't working properly and I had to take to the shop to correct the problem. 
------------- Unfortunately the two previous answers will not cause the coolant to spew out when you shut the engine off. The only thing that will cause that is excess pressure in the cooling system. Just about the only thing that will cause that is a head gasket. Most Cadillacs from the early 80s on have aluminum heads. It is very commom for an aluminum head to become warped when the engine overheats. When this happens a crack can form between the head gasket and the top of the cylinder block allowing pressure to get into the coolant. This in turn may cause a coolant hose to expand and allow coolant to spew out, it can also cause the radiator cap to release coolant, a good radiator cap is designed to release pressure when the pressure goes above the designated psi. The fact that it is not boiling over while running indicates that most if not all the rest of the cooling system is allowing the water to flow. The most common cause of overheating in engines is that the thermostat gets old and sticks. It only has to stick one time to cause the engine to over heat enough to either damage the head gasket or even cause a crack in the cylinder head. Take the vehicle to a garage and have them do a pressure check on the cooling system. After they have applied pressure to the system they will allow the engine to cool for a short while. If the pressure drops very much they should then remove each spark plug in turn and check the cylinders to see if coolant is in in them. If so that is the evidence that the head gasket is bad. If there is coolant in the crank case oil pan also, that indicates that either the head gasket is completely gone or that the cylinder head is craked. Depending on your goegraphical location it could cost around $1000.00 or more per head to have the heads milled and the head gasket replaced. If the car is over 8 years old or has more than 100k miles on it you will be better off to have the water pump, timing chain, camshaft and crankshaft timing gears replaced at the same time. Depending on the cost of such you may wish to check with someplace such as Dr. Motorworx to have the entire engine replaced. It can sometimes cost less to do that. And these shops usually not only garrunty their work, but usually give anywhere from 1 to 3 years or 36k warrunty on the engine. I hope this has been some help to you. GOD Bless! GLORIFY GOD!------------also this is someones personal experience.

SOURCE: water leak inside the car

Whats causing this is that the drain hose for the evaporator is clogged and overflowing into the car. what has to be done is get under the car and find the drain hose, which is going to be on the passengers side of the car by the firewall, and get either compressed air and blow into the hose to try to free the blockage

SOURCE: Water on floorboard caused by heavy rain. possible drain plugged up. How hard is it to fix myself.

The plastic cowl that goes between the windshield and the air intake inlet for the cabin blower motor needs a seal added to it. Go to a hardware store and get a thin 3/16" thick or less weatherstripping seal and place this on the plastic cowl piece. There might already be some there from the factory but it is most likely hard and cracked. This will keep the majority of the water from running into the air intake box. Also there is suppose to be a rubber seal on the edge of the sheetmetal just above the air intake. Make sure that weatherstripping piece is in place and not torn in any way.

What is causing water to leak down onto the passenger side floorboard of my 2004 Mazda 6 wagon when I have AC on?

Feel the water and smell it. If it smells sweet and fells oily, is is coolant. If is isn't oily and has no real smell, it is water. There is a tray under the evaporator and heater cores that catches water/coolant and drains it via a tube thru the firewall to the outside of the car. This tube is probably clogged and needs purged. If you have coolant on the floor, you'll need to replace the heater core. If it is water, purging the hose will solve the problem as the water is just condensation from the AC coils

Would the A/C cause water on rear passenger floorboard

Usually if the drain tube for the AC is plugged the front passenger floor gets wet, not the rear.

95 buick roadmaster is leaking water in the floorboard

If the water is clear and has no antifreeze smell, then its a blocked condensation drain from the AC. Most likely. You should be able to clean it out quite easy. It will be in front of the passenger side feet area. You may be able to see it from under the hood, or you may have to go from under the car.
Look for a crinkly tube sticking down or it may be a 2- 3 inch downturned L shape tube on the firewall. A pipe cleaner from any tobacco shop will do the job. Just poke it through to clean out. Watch out for water in the eye.

If the water is greenish or orangeish, and feels sticky then you have a heater core leak and will need to replace the heater core.

The AC evaporator is leaking on my 97 grand cherokee. Floor boards full of water. The evaporator was replaced 2 years ago. What should I do?

The drain tube for the evaporator case is plugged with various debris which allows the normal accumulation of condensed water to overflow the case onto the floorboard. Run a brush or similar tool into the tube which should immediately drain the cavity. If you catch the water in a pan, inspect it for debris. This should work ok for a year or so, then re-clean the drain as needed. The more the AC is run, the more debris will accumulate. Hope this helps!

I have a 2003 Volvo S60 that ends up with a wet carpet in front of the passenger seat whenever it rains (Seattle). Also, when I am driving and turning left or right at corners, I can hear water sloshing...

The drain for your A/C may be clogged causing the water to accumulate. You should be able to locate the drain from under the vehicle on the pasenger side, perhaps there is an accumulation of debri such as leaves for example. Also, sunroof drain may also be blocked. I can say I have seen this problem before, and its a good place to start. Good luck

Wet on Passenger side floor when AC is on

Auto ac units have an outside drain for the condensation. If you ever noticed a car running and it looks like it's leaking something on a hot day it's the condensed water from the ac unit draining. What you have is a clogged or disconnected drain hose.
You need to find the hose and drain and reconnect them. Sounds simple, good luck.

2005 Chrysler Pacifica-Air conditioning leak

The 05/04 Pacifica did not come with an elbow tube on the drain line for the AC drip pan. As you drive, the air flow into the tube pushes the condensate water back into the pan which is inside above the passenger floor board, the drain line is under the hood on the firewall. I spoke with the parts guy at the local Chrysler dealer, he sold me a drain tube for the 06 (~$10) and I installed it, wasn't too hard to do from the top if the engine is cold. The elbow slips on over the drain tube. Make sure to point the tube down. It only took one trip to start seeing water drip out of the tube and the floorboard started to dry up and almost three years later, the floorboard is still dry.

Water leak

The drain is an opening on the passenger side of the car on the firewall towards the bottom.
