Condensation water from air conditioner soaking front and rear passenger carpets. Where is drain located?

Hi there sounds like the drain for your air conditioner is blocked, what you need to do is find a little rubber hose extruding from the firewall under the bonnet and stick a long thin woe up it to clear the blockage, hope this helps

I have one of these, it did the same thing. I found the sun roof seal had gone hard ( due to the u.v from the sun ) and was not sealing properly.
Th drain hose from the cavity was blocked, the water ran down the door pillar and on to the fire wall and out behind the carpet.
Allso if the air conditioning condensation collector drain is blocked water will find its way the the carpet. the drain should empty to the ground.

Sounds like a classic example.
The drain hose or tube should be near the bottom of the firewall where it meets the floor on the passenger side.

no it will most likely be a blocked drain pipe that goes into the engine bay from the A/C and drains the condensation created by your car's air conditioner. A mechanic workshop can do a blast of compressed air by your mechanic and free the blockage takes about 30 seconds to do with a car hoist.
If it is humid conditions the problem will be much more and you might find the front demister won't work due to water sitting on top of the Air conditioner. It will heat this water and blow steam on your window.

Either your heater core is leaking, is the fluid sweet smelling and slimy? Or the condensation drain from your air conditioner is plugged causing the condensation to drain inside as opposed to outside. Or the glass seal is bad and rain water is coming inside from around the windshield. Heater core is going to need a repair guy, condensation drain can usually be fixed in about 5 minutes at any shop with a lift, glass leak you are going to need an auto glass shop's help.

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!

There is a rubber drain hose that should be attached to the bottom of the cooling/ blower unit on the passenger side of the car underneath the dash. This hose drains the condensation from the cooling unit. the hose may have gotten disconnected or it may be clogged up. I have had cases where a dirt dobber built a nest up inside the hose and clogged it up. Check this hose it may be the cause of the water puddling up in your car.

The issue is condensation from your air conditioner not properly draining. This is usually caused by a damaged, or clogged drain hose. The condensation is supposed to drain outside the vehicle by way of a hose on the firewall area.

sounds like the air conditioning drain for condensation is plugged

It sounds like a plugged drain line from the air conditioner. Most cars now run in the a/c mode whenever u turn on the climate control (even when heat is on). The passenger side front is where it would be wet, and the carpet and carpet pad act like a sponge and will soak up the water. Let me know how u make out.
