Yes there is a drain under the car on the passengers side.You will have to jack up the vehicle to look for it.It will be a small rubber tube.Use a small screw driver or something to loosen the debris that is clogging the drain.Be careful and do not use anything that is to long that could poke a hole in the evaporator or heater core.Hope this helps.Good luck.

2003 STS cadillac leaking water on both driver and passenger floor boards


It could be the sun roof. It also could be clogged drains from the sun roof. It may also be door seals Leaking. It could also be leaking around the bottom of the windshield. A good way to narrow it down is to get inside the car and have someone spray the outside of the car with a water hose. while you look for water leaking inside of the car. If it does it while the ac is on may be a clogged ac drain. however it usually just leaks on passenger side when it is that. well good luck.

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


this will be condensate from the fins of the ac evaporator in the car and is leaking onto the floor because the drain on the unit is blocked either in the hose or at the bottom of the ac box

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

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.

I have water leaking onto the carpet on pass, side front & rear and I assume the drain for air cond is pluged. I don't know where the drain is located or how to unplug it. it is a 2003 cadillac...


i believe you have a leaking heater core, if the water is leaking out from under the dash right under the glove compartment this is almost certainly the problem

I have a 2001 DEVILLE. I am getting two inches of water on the floor in from of the back seat on the passenger side of the vehicle. Nothing is visably wet anywhere but on the floor.


Is it wet in the front passenger also? I had this problem a few months ago and 1 of the gurus from here told me to check the ac drainage hose under the vehicle...it was clogged. Other than getting soaked once i unclogged it, it was pretty easy. Good luck

Water is leaking back to passering floor when ac is on were is the drain if any how to stop it


The ac drain hose is either clogged up or missing, causing the flow of water on the passenger's side floor. Have the drain hose checked.

Getting water in front passenger floor boaed, what might cause it?


Clogged or disconnected drain hose from the heater core box. Or bad/leaking heater core. Does the liquid smell like coolant. If so bad heater core. If not and the water only when you use the AC then it is a drain hose issue. If neither of those pan out you could have a leaky windshield. However 99% of the time a wet passenger floor is caused by a bad heater core or drain hose.

Water on passenger floor...


Two things: If there is a stickiness or sweet smell to the water, your heater core may be leaking.
If this is just a summer thing, your a/c evaporator drain tube my be blocked/clogged or leaking inside the vehicle.
