Why does my 2004 Saturn Ion AC leak water into passenger side floor?

The condensation drain line has either gotten plugged or has fallen off.

The component of an A/C system that makes the air cold is called the evaporator, logically it needs to be in the air-conditioned space. In cars it's nearly always in the dashboard on the passenger side.

Warm air holds more moisture than cold air, so as air is circulated through the evaporator to cool it, the moisture in the air condenses back to liquid, like a mini rain shower in a box. That water, usually called condensate, has to go somewhere so there is a hole in the bottom of the evaporator and a tube to carry it out of the cab, through the firewall, into the engine compartment and onto the ground.

If the tube becomes plugged, condensate will accumulate until it overflows an air vent. If it comes off or cracks, the problem is obvious. It's pretty common for a condensate drain in a car to plug, junk falls into the intake vent that won't fit down the drain.

Clearing it would be simple if getting to it wasn't so involved, check your service manual for details.

Why does my air conditioner leak water on passager side floor

The Evaporator box has a Drain tube, this is blocked and not letting the water drain off ,hence the build up of water in the box which will overflow into the passengers side .
The drain tube needs to be unblocked to let the water drain off.

Wet passenger floor board/2004 Envoy

The moisture drain for the air conditioner is there. When it plugs up, excessive humidity removed by the A/C will leak out onto the floor board.

Is it normal for a car to drip water on the ground after running the air conditioner?

Yes, The air conditioner evaporator core inside the vehicle is very cold when the a/c is operating and moisture will condense on the outside of it, especially on a humid day. This moisture then trickles down the sides of the core and collects in the plastic housing beneath the core where it then escapes through the evaporator housing drain tube and drips on the ground beneath the passenger side of the chassis. The more humidity in the air the more moisture you will see dripping onto the ground. If the little drip hose should ever get plugged up this water then will overflow the housing and drip on the passenger side carpet so if you ever have that problem you'll know what the cause is.

Water leaks on the passenger side carpet when i run the air for an extented time on my 04 gmc envoy

The evaporator for the air conditioning is under the dash on the passenger side. Open the hood and look on the firewall for a rubber hose that sticks out of the firewall. This hose is to allow the water to run outside and onto the ground. Sometimes they plug up and the water can't get out so it builds up and drains onto the floorboard. Hope this helps...

Water on passenger side floor board and carpenting

Might be coming from the air conditioner evaporator drain hose. It goes out from the cabin to under the hood just in front of where the passengers feet would be. It drains water to the ground, and may be plugged. It is a little hard to find.

Leak to the passenger side floor board.

there idef. a drain for the water and is located below heater box on pass. side under vehicle. usually rubbertype hose with sort of closed off end maybe 2" long. (sometimes they are hidden, look carefully) i use shop comp. air to clear but a straight piece of wre may be just as good. also consider replacing cabin air filter behind glove box. probably restricted as well
