You need to go under the vehicle and unplug the rubber drain for the a/c.The drain can somtimes be reached under the hood on the passenger side fire wall.

    Do you have any further tips if it is determined by GMC not to be the drain/plug?

What is leaking on the passenger side of 1997 range rover....


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.

I have a Mazda B2500 (2000). Everytime it rains the drivers side floorboard gets soaked. There is no dripping or water running down the door. What could this be?


You could have a windshield that is leaking water. Often this water will trickle down from the bottom/inside of the glass and then down the firewall, under the carpet or floor mat, and to the floor. The way I usually hunt for these is to remove the floor mat or carpet then get a flashlight and lay down in the cab so you can see under the dash area while someone sprays water on the vehicle with a garden hose. Often the leak will show up as a trickle that you can then backtrack to it's source. Another spot to look for is at the cowl in front of the windshield where air for the heater and a/c is pulled into the passenger compartment. The water drain holes in this area can plug up and allow water to overflow into the passenger compartment. Good luck, hope this helps!

My floor boards in my Cavalier are Soaked ..


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!

What would cause wet carpet and water on the passenger side floor


there is a leak because the foam has disintegrated, or the seal has broken open down by where the feet of the passenger is. Rust stains tell me that the leak may be caused by a break in the body somewhere.

Try spraying expanding foam in the area between the plastic and the metal parts to try to seal out moisture from coming into the passenger compartment.

Water leaking into 2005 Camry 6 cyl under carpet drivers side.


I think that I can help you. It sounds like your drain-tube is plugged up. Get in the passenger side, and pull the carpet back from under the glove box. Look for a black rubber pipe that goes from a black box, and pokes thru the firewall, on the passenger side. Remove the hose from the box, and have a container ready to catch water. If water comes out of the black box, your drain hose is plugged up. Clean out the clog, and you will be golden.

My dad has a 2004 Dodge Dakota with the exact same problem, the passengers side floor board is soaked with water after running the AC. Also there is a pool of water that collects under the truck.

We are getting a mechanic to look at it, I will post what the problem is when we find out.

Water leak passenger side in dodge caravan 2005 carpet soaked


look at the firewall on the engine side and you will see a small stub hose coming out on passenger side about even with the bottom of the heater box inside. that hose drains condensation from the ac...clear it out and you will have a dry floor. (unless heater core is leaking but you didn't mention any overheat or coolant loss so likely that's not a problem)

There is a water leak somewhere in my 98 toyota camry that leaks into my passenger side floor. There is no sun roof and no visible leaks from the windows or doors. Any thoughts? A/C leak maybe? water...


I am the original owner of camry xle 1998 with wet floors. In 2000 I had drivers side door seal leaking at welt. Removed old door seal and new weather strip on drivers side installed. The door panel was never wet, but wet at bottom of door where there are drain holes...slowly leaking under carpet.
In 2001 later water again. Coming from overflowing A/C evaporator-drain plugged/ tank full of debris. Removed evaporator, cleaned + drain cleaned.
In 2003, driver door seal against window rotted. Removed door panel and found leak at window belt molding at the mirror joint inside + out. Lots of mold under carpet needed to replace! Made a fuss at dealers for reacurring problem and they replaced the carpet for free.

Floor on passenger side gets wet when running air conditioner


I have a 2006 Fusion with the same issue and I fixed it for less than $2. There is a drain tube that goes from the passenger floor board out through the firewall to allow water to drain under the vehicle. However, water can travel along the underside and seep back into the vehicle. I went to a hardware store and bought a few inches of 5/8" tubing. I simply slipped this onto the drain and the water now flows down the tube and safely away from the interior of the car. Been dry ever since.
