A/c evaporator case large amount of condensation water on outside of case dripping on passenger floor

I have cleared the drain even though it was draingin fine, still have issue, it is so bad water drips into the glove box itself, any ideas would greatly be appreciated, I believe the previous owner has tried to fix this by drilling many holes in the case, 6 to be exact which I will have to seal off, thank you ahead for any input.

The problem most likley is caused by the extra holes drilled into the case. The previous owner should have just cleared the gutter out and left it at that. Because there is extra holes the condensation is going to come out of them holes.

Do you live in a very humid area? I have never seen any condensation on the HVAC housing of my jeep. But drilling holes in the housing for sure was not a good idea, because the condensated water on the inside of the HVAC housing will drain inside the jeep.
I would start closing those holes first and then see what happens.

One of the most common problem is back pressure from engine compartment. Seal all the holes, and fit long curved hose on the drain. Ziptight the hose to the frem and let run for a wile. If water leacking from tha case you need to remove and seal.
Good luck

It may be that hot air is some how getting in and around the evaporator, from the holes that was place there earlier..Also has someone check the a/c pressure to make sure you do not have a blockage..like may be the line filter is clog or needs changing ...

Check your cabin air filter, you may find that a mouse has built a nest under the filter and partly plugged the drain. You may need to use a mirror to see for damage. Clean area and install a new air filter.

SOURCE: A/ not draining, dumping water into Pass/side floor board. Can't find a drain?

SOURCE: leak onto floor passenger side from neck of ac drain through firewall

It's not your heater core. If your heater core is out it would leak antifreeze. My wife's 97 Grand Cherokee had the same problem. It is condensation from your AC coming leaking through a round hole in the AC unit at the firewall. Pull the carpet back and dry out underneath it, there will be a lot of water and we had to leave the carpet pulled back with a fan blowing on it all weekend to dry out. I fixed this about 8 years ago so if I remember correctly, the was a plastic part of the AC at the firewall that had a hole in it that the water was coming out of, I could see leaves and debris in the hole so I know it was part of the drain system. I cleaned out what debris I could and used a cone shaped peice of rubber and twisted it in to plug the hole and tapped over the plug to ensure that it wouldn't back out with vibrations, etc. After you dry everything off start the engine and turn the AC on max, you'll be able to see the where the water is leaking from after the AC gets cold. Hope this helps, it drove us nuts for a year before we figured it out and the wet carpet smell wasn't pleasant.

SOURCE: 1997 Jeep Grand Cherokee with water in the floorboard

Yes but drill the hole in the passenger compartment on the bottom of the box where it slopes down to the drain. Blow out the hole with compressed air and then plug the hole with a rubber plug or silicon. If you use silicon let it dry for a least 2 hours before running your air conditioner. Now if it happens again you have an access hole to clean out the drain. You want to drill the hole toward the firewall like you were drilling toward the drainhole.

SOURCE: Water leaking onto floor from air conditioner --

Yes, it usually exits out on the right side (Passenger) lower firewall, and drips water behind a little of the right front wheel, inboard a little. If the drain tube is plugged, it can run inside, so check that first. Poke something up the hose, just not anything that may damage anything. (A long plastic zip-ty strap)

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.

2002 Tribute water collecting on floor of cabin passenger side


SOUNDS LIKE YOUR A/C EVAPORATOR DRAIN IS PLUGGED. WHEN YOUR DRIVING THE EVAPORATOR WILL COLLECT CONDENSATION AND THEN DRIP OUT OF THE DRAIN. THE DRAIN IS LOCATED NEAR THE FIREWALL ON THE PASSENGER SIDE OF THE VEHICLE. SOMETIMES LEAVES OR MOLD/MILDEW WILL COLLECT THERE SIMPLY SHOVING A COAT HANGER END OR SCREWDRIVER WILL UN CLOG IT AND ALLOW THE WATER TO DRAIN.

I noticed that my passenger side floorboard is wet, what would be causing it?


there's a few different things that could be causing your floor to be wet, one is your heater/air conditioner unit has a drain tube on it to drain off condensation out of the box (inside the car) that contains the heater core and air conditioning evaporator, it is designed to drain to the outside of the car near the engine area, they often become plugged up with debris which don't allow them to drain though the hose and then begin dripping inside the car on the passenger side, the other possible case is that the windshield has been replaced and not sealed properly and water is entering around the windshield and dripping on the floor.also there is a minor possibility that water is entering around the door seal, although unless there has been damage to the door or door seal is very unlikely. thanks for using fixya

Water is collecting on the floor of my 96 grand cherokee


If it is on the passenger side and only when a/c is on then you have a plugged drain tube on the evaporator housing. Locate the housing under the hood, passenger side - mounted on the firewall. This is the housing where the a/c lines enter the cab. On the bottom of this housing there will be a rubber tube that is to carry away the condensation from the evaporator core to the outside. (Ever see water dripping under the car on the passenger side when the a/c is running? This is from the drain tube.) Sometimes the tube is hard to see without raising the car in the air. Only do this if it can be done SAFELY. DO NOT get under the car with it only on a jack! Locate the drain tube and clear of any obstruction (usually mud).

Water in drivers floor after a/c use


condensation builds on the evaporator coils and fins. they drip into a pan and drain through a hole in the pan, and down a tube to the outside. that's why you see water dripping on the under side of your car on the passenger side. the tube or hole is most likely clogged

The evaporator drain is plugged with debris and filling up the heater case. Remove the 90 degree elbow and clear the drain hole at the case.(pencil or piece of wire) You will know that's it when it dumps out a half gallon on the floor. Be sure to reinstall the elbow to keep out rain/ road spray.

Location of ac drain to try and stop wet floor board on 98 tj?


The problem is with the evaporator drain. There is a, (usually soft flexable), tube that drains condensation from the evaporator to the outside. It is located in the passenger compartment, under the dash. The hose has, (A)-became disconnected from the evaporator. (B)- Has gotten a kink in it. (C)-Became clogged, causing the evaporator to overflow into your passenger floorboard. Your vehicle probably has some covers over these components, you will likely have to remove. Locate the hose, it typically drains just behind and inside your right front wheel. It may be concealed behind a kick panel, or may go thru the floor or firewall. You must find it and follow it to the evaporator and make sure it is not clogged or kinked and is properly connected to the evaporator.
