I know its a year later, but i went through this today. found out the problem is simple to fix. you have the black engine cowel just below the windshield. when you take the wipers off, and the screws out and lift that piece out you will see the white grommets that the screws screw into. they have a gasket that is under them that rots out. the 2 first passenger ones sit right above the fresh air intake for the a/c. take them out, clean it and use some rtv silicone to seal them up. put it all back together and let sure for a day before you test it.

It may be leaking through the evaporator intake vent... There are no TSB's for any kind of water leak in 2000, you may just have to start disassembling stuff until you find where the water is originating from. It's probably something stupid, but check any rubber grommets, harnesses, the evap intake port, anything you can see that goes into where you can get it to leak from.

My 1995 honda civic has water coming out from below the dashboard on the passenger's side. What the probable cause of this and how can I repair it myself. Thank you.

sounds like the the heater core. are you losing water from the engine, if so this would be the problem, o if it only leaks when ac is runnibng you have a drain that's probably plugged (usually a rubber hose under hood monted to heater control box. unplug it, if it's the heater core, possibly removeable under hood, but most likely under dash on inside,

Water on floor passenger side after it rains and after air has been running 2000 grand prix

Ac hose leak?
leaking heater core?

Hint: it leaks when it RAINS

If it were related to the heater core or the AC drain, it would be leaking when it is not raining also, so those diagnoses are not logical.

The grand prix has a long history of floor leaks from seal failures around the air intake under the windshield cowling, where RAIN water runs in.

If the water comes in from under the dash, the drain under the air vent on the hood is probably clogged. You have to take off the windshield wiper arms, remove the vent and unclogg the drain. Very poor design!

2003 lancer es when my ac is on water leaks on the passenger side under my dash ?????? what can it be and if anyone knows how can i fix it???? help please thanks..

You have a clogged drain hose. To repair you need to look under the dash and you will see a small hose that comes ouit and goes into the floor. This is your drain hose. Pull off the end under the dash and clean out the hose then reinstall. After you have done this to check and see if repair worked or you need to clean out the hose more. Start the car and turn the AC on and watch under the car on the passenger side after it runs awhile you should see water dripping under the car. If it does you have fixed the problem and your AC will work better as a bonus.

Water collecting in driver side pass. compmnt - AC cndnsr drain?

Clogged AC drain hose.

You can see it by opening the hood and looking towards the back firewall.
Its a short black drain hose and will have a good rust spot under it.
To see it in the car you need to remove you dash. Lower your dash. Remove the screw on the right side and you can pull your dash out. The drain hose is located in the upper left side near the center hub and right near the engine firewall. Its a 6 inch black hose with a few bends and stubs out through a hole into the engine compartment. You can easily pull it out. and stick a short screwdriver up into the drain pan to clean it out.

Water leaks into car due to clogged air conditioning hose

They are not always easy to see and they differ in length but yes they are typically on the passenger side firewall and may extend down towards the lower firewall or just drop out an inch from the firewall. a coat hanger is not always going to work and you will need to be careful not to put a hole in the evaporator that sits just inside from where that drain comes out. it is possible that the lower cover where the condensation is collected has a crack and may not be pluged at all. look above where it drips on the floor and see if there is any sign of damage to that cover. You may find that it is easier to take off the cover and clean. that will just depend on your confidence in dismanteling that part of the dash and heater box.

Water Leak UNDER the Vehicle.

It is definately your AC water outlet. The hose must have shifted sort of.

Water leak in 1995 Jeep Wrangler SE

There is a drain for the vent air box under the hood on the firewall. Open the hood and look on the left side of the engine for a rubber tube hanging vertically from the firewall. This tube gets filled with crud (leaves, dirt, etc) and plugs up keeping the water from draining until you turn a corner and it spills over into the cab... on your feet. Been there done that.

The drain has a **** in the bottom- pull it up, squeeze it at the end and use a screwdriver or similar to clean the end out.

Forget windshields, firewall sealants, and all the other remedies suggested all over the internet for water leaks until you look at this- it's the cause 99.9% of the time
