SOURCE: water leaking from back of engine compartment

More likely the heater hose. Most run back behind the glove box. It could also be a leak in the heater core- normally that would fog the windshield on the inside.

The condensation drain is plugged in the heater/AC plenum, the drain is under the hood at the very bottom of the firewall on the passenger side.

SOURCE: water leaking from evaporator i have cleaned out

Try removing the cowling cover under the hood. There is a cabin air filter under there. See if there are any leaves, etc. built up in there. There is also some concerns that there may be a blockage in the drainage system surrounding your sun roof, if you have one. Check that also. If that does not work, you can also park with the nose of the car facing downhill somewhat. That always works for us.

SOURCE: water leak on driver's side floor

It's either the driver's side door seal or the windshield leaking. Best bet is to be inside on a dry day and have someone run a garden hose over that side of the car. That will give you your answer.

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.

WATER IS LEAKING INTO RIGHT FRONT FLOOR


I had the same problem on my 98 Century. Turned out when I had my oil changed, they dislodged a rubber "gasket" ( a foot long piece of rubber ) mounted on the firewall seam right in front of the passenger compartment air filter box under the passenger side windsheld wiper. It diverts water from the windshield so it doesn't flow into the fan blower box and onto the floor. It's a crappy design. If it's not in place all the water runs into the car. I had two inches of water on the floor, had to pull up and wring out the soundproofing, hit it with a hair dryer ( took two days to dry ), same for the rug. Put some silicone in the slot on the bottom of the rubber piece and set it on the firewall seam. You should see where it was originally. Good luck.

The drain on your evaporator core housing is most likely plugged. Condensation on the evaporator core drips down into the plastic housing and drips onto the ground through a hose on the firewall on the
passenger side.

Find the small hose on the firewall in the engine compartment. You should be able to pull off that
hose and see if its stopped up. If the hose is ok, you may need to remove some of the ac ducts
under the dash to get to the evaporator core housing to unclog the drain hole.

I have no doubt that thats the problem.

Water leaking into passenger side of floor


This is when the air conditioning is running? The ac evaporator csae drain tube may be plugged The tube is located on the passenger side firewall.Generally I will use a small pick to dislodge debris from the tube being extremely careful not to go into far as the evaprator core may become damaged and develop a leak.

your a/c evaporator drain is stopped up or blocked off can be seen at firewall area on passenger side looks like a short black hose coming out of firewall and turns down with nothing hooked to it if this gets restricted the blackbox under your dash fills with water and eventually leaks in floor you can try and run small piece of wire up hose to unstop but be careful not to punchure evaporator core

My ac is cold, but i have water on the passenger side


Very simple solution. get underneath your vehicle and try to put unsharp object into the A/C drainage holes as they are blocked. That's why the water overflows inside the car. worse senario you got a crack on the Evaporator Housing which is very very rare case.

Water leaks into car due to clogged air conditioning hose


They are not always easy to see and they differ in length but yes they are typically on the passenger side firewall and may extend down towards the lower firewall or just drop out an inch from the firewall. a coat hanger is not always going to work and you will need to be careful not to put a hole in the evaporator that sits just inside from where that drain comes out. it is possible that the lower cover where the condensation is collected has a crack and may not be pluged at all. look above where it drips on the floor and see if there is any sign of damage to that cover. You may find that it is easier to take off the cover and clean. that will just depend on your confidence in dismanteling that part of the dash and heater box.
