Does it do this all the time or only while running the air conditioner? There are two possibilities. One, when the a/c is running, water condenses on the evaporator and it has to drain out of the box via that hose, this is normal. Two, your heater core is leaking and this is where the water is coming from.

Water leaking passenger side

Your AC condenser drain is clogged up, it is on the firewall in front of the passenger, engine comp, look for a little hose sticking out or a drain, get a piece of wire in there, probably gummed up or got bugs in there. The water should spill out once you get it clear. Hope this helps.

Why does water leak inside the passenger side of my 2001 mitsubishi montero from my air conditioner?

your a/c evaporator drain is stopped up or blocked off can be seen at firewall area on passenger side looks like a short black hose coming out of firewall and turns down with nothing hooked to it if this gets restricted the blackbox under your dash fills with water and eventually leaks in floor you can try and run small piece of wire up hose to unstop but be careful not to punchure evaporator core

Where is the air conditioning drain hose for a 2003 Mitsubishi eclipse

It’s in the hardest place to reach they could put it. Get under your car and follow the firewall near the center. You'll see a small hose poking out that you can barely reach with an air hose wand. Debris often plug the drain hose. If you hear water sloshing on the passenger side in the dash and/or the passenger side carpet is soaked, blow air through the drain tube to unblock it. Also the grommet around the hose there at the firewall can deteriorate and let condensed water blow back into the driver’s side floor pan. With a lot of effort you can pack silicon sealant around the drain tube at the exiting firewall location and solve that problem. With real effort you can place silicon around it from the interior also. If you don't have a compartment filter or your filter is old and ineffective, you'll be amazed at how much debris sets on your condenser coil down there in the center of the dash (if your airflow is less than you remember and not as cold, the condenser coil is likely covered in debris)...and it's almost impossible to clean it out without disassembling the dash. That's another story on how to fix...

2003 galant leaking water under glove compartment when i make left turns. any advice? the car has no signs of over heating or any other problems. just running water flowing during left turns.

Is or has your a/c been running?If so, open the hood and on the passenger side on the firewall, there is a blaxk jousing.. Slide your hand under it and you will feel a rubber thing that is flat on the end, Squeeze it like a coin purse to open it. It's the A/C condensate drain.. That should fix your problem. Good luck, Now you can turn left again, but no right turns now. Just kidding.!
