Question

When I turn my AC on in my car, it leaks water on the passenger floor. what is the problem?

Answer 1

the drain is plugged. look along the firewall

Answer 2

The drain is plugged up. Use a stiff wire or plastic rod to unclog it from under the car.

Answer 3

Yep, check the drain hose, and check along the inside firewall fron under the engine area and see if there is a blockage.The Hose can be pinched or blocked with foreign materials.

Answer 4

Water condenses on your AC's cooling coils, like it does on the side of a cold soda can.  The little hose that drains that water out of your car must be blocked.

Look up in the service manual for your car where that hose attaches.  Take it loose and gently poke around in the hole with something like a breadbag tie (nothing too rigid - don't want to damage the fragile fins of the evaporator) to make sure there isn't any shmutz blocking the hole, then blow out the hose to be sure it's clear.  Reattach everything and you should be good to go.

Answer 5

blocked drain for air conditioner,check under car for blocked pipe

Answer 6

I can think of two causes, One is that the drain o*****e is blocked. just like noted in previous posts; the second is the evaporator tray/box cracked.

For either cause, a visual inspection of the unit is required.
