A/C and water in passenger side

[FRENCH_CAMAROV6]

When I put A/C on, there's is water drop in my car, in the passenger side.
It comes from the center of the console.

What can I do?
What's the problem?

sounds like heater core.

[FRENCH_CAMAROV6]

heater core? are you sure?

I've got water only with cold air not with warm air...

sounds more like the drain for the evaporator/condensor is blocked.

where is the drain?

I haven't found it on the car and on the manual part

the drain should be on the firewall (engine side) on the passenger side of the vehicle. it should look like a short plastic tube sticking out about 1/2" - 3/4" (thats 12mm-15mm in the metric world). it almost seems it will almost drip on the exhaust crossover pipe.

a way to check this would be to turn on the a/c and drive around a bit. park the car (with the a/c and engine running) and open the hood and take a look (look out for the moving/hot parts). if you dont see any water dripping from the around the firewall area something is wrong (it will help if the day is hot and humid of course).

some other questions i suppose are in order. does it also drip water when you use defrost? how much water are you getting? does it have a strange odor/color or does it just look like water? where does it leak from? remove the kick plate from the passenger side of the dash to get a good look at the evaporator and heater core.

I used to have water under my car when put A/C on but not anymore.

It's on the car now, a few drops, and now a swimming pool at the feet of my passenger after a 120 miles trip with a/c!
No special color or special smell, it ain't the coolant liquid

I have to find the short plastic tube this afternoon!

[FRENCH_CAMAROV6]

I found it! it's just a hole.
There was leaf into it.
I've put a A/C at MAX and the water fall under the car, not into
Thank you!

at this point i would like to grumble a little about gm engineers and the simplest of problems. leafs easily get into the fresh air intake and wind up inside the ducts of the dash.

2-3 times a year i need to drop my blower motor and remove the leaves trapped inside.

why or why cant they design a screen to filter leaves?

glad you found your problem. typically leaves dont get past the heater core and the evaporator core to block the a/c drain.

This happened to me just a couple of days ago. Fortunately the dealer was able to take care of it quickly under warrenty. I had a little over an inch of standing water in my passenger footwell. I first discovered it when I took a hard right hand turn and my right foot got doused with cold water. I normally take care of stuff like this myself but when it comes to A/C I don't know very much about how it works. In the end, it turned out to be that drain was cloged.
