Floor on passenger side gets wet when running air conditioner

Often the floor of the passenger side become wet if the drain pipe of the evaporator is:
- Bent or twisted.
- Clogged or,
- There is any obstruction in its routing.
The drain pipe is a rubber hose about 14 mm in diameter, located just under the evaporator (cooling coil) casing on the passenger side.
The most easiest way to clean the pipe is to take it out, wash it from inside with water or to blow a compressed air slowly through its distal end while leaving it in place under the body.
Note: Keep your eyes away while blowing the air.
Hope that it works.

Sounds like the a/c drain is clogged up you need to look on the firewall near the bottom behind engine pull drain stop of and clean it out and see if that takes care of your problem .

your heater core is bad they leak when they go bad youll have to replace its under/behind the dash

Use a long Zip or Wire tie to run up it...

the drain for you ac is clog up and needs to be clean out or its you heater cor needs to be changed

Look underneath the passenger side around the firewall area. You can use a straight rod to run up into it to break the clog free and start draining.

If you've been using your air conditioner during this time, and it hasn't rained at all, then the small drain at the bottom of the a/c evaporator core may be plugged. When you use the a/c to cool the car the evaporator coil [located next to the heater core in the ductwork under the dash] is very cold and moisture from the hot humid air condenses on it as a result. This condensation dribbles down the core and accumulates in the plastic housing under it where it should then drain out a small hole and drip onto the ground. If the small drain gets plugged, which happens quite often, then the water fills up the housing until it overflows and then runs out and soaks the carpet on the front passenger side. The drain is located on the engine side of the firewall, passenger side, down low where the firewall begins to curve under. Usually a puff of air will clear the clog and the drain will work fine again. If the carpet is really wet it would be a good idea to remove it and get everything dry again as it tends to get pretty smelly if left wet. One last note: usually a leaky a/c unit will only make the passenger side carpet wet unless it's been leaking for a long time while a leaky windshield seal can make both sides wet depending on where it is leaking. Good luck, hope this helps you out!

The air conditioner condensation drain is under the hood not inside the car. The fluid is probably a leaking heater coil. It is located on the passenger side firewall.

the evaperator drain tube is plugged,blow air through tube to free obstruction,you gain access from the engine compartment on passanger side close to exhaust,

The drain from the a/c under the dash is plugged up and needs to be cleared. If you check from under the vehicle, u should be able to find the end of the drain tube on the passenger side, behind or near the front wheel. Carefully run a wire up the tube to dislodge the obstruction (goop build up). You can also use compressed air.
