Sounds like a heater core leak or a hose leaking at the back of the heater. Put your finger in the water and taste it. If it is sweet it is anti-freeze and it is leaking.

Even when not driven i find water (lots 1/2 or more) in the floor boards both front and back both sides why?

Condensation leads me to believe you have a broken heater core. They are made of plastic.

Water on floor, can be the core, or bad seals on windows or moon roof.

If the water tastes sweet, it is antifreeze. Don't ingest to much as it is toxic. :>)

2008 mustang water. on passenger floor board when it rains !

Sounds like the windshield is leaking. Run water over the windshield and have someone get inside car and look for the leak. Alternatively take it to a reputable windshield repair shop and have them check it.

02 taurus condensation pools in right floor, just need to know how to fix. Its not the rain.

Look under the car, under the right floor board toward the front for a small rubber tube, this is the a/c condensate drain tube, it coould be on the right side firewall under hood close to the bottom. Dirt wasps love to build nests inside these tubes, they become plugged and the condensate runs inside on your floor board on the right side, to clear it, grab ahold of it and squeeze it along the length and gently twist it back and forth, then operate the a/c and see that water is coming out of it. Hope this helps, let me know.

The passenger side floorboard gets wet =

is it only when the ac is on? there is a pan under the ac unit that has a hole in it to allow the condensation to empty. if that hole gets plugged it could cause the condensation to build up and back into the inside of that car. i unplugged mine and floor stayed dry

Water accumulates only on the front and rear driver side floor boards and "only" after it rains. I was told it might be a plugged drain. How can you tell if its a plugged rain drain and not a poorly sealed...

take a star screw driver and punch a pair of holes in your floor on drivers side make sure once you go through push the screw driver towards the front of the car and creat angled pockets
these will be your new drains being so small they will bnot tako on water or they will take on a min of water and they will drain the floors

it''s the easiest way to fix the problem go right through the carpet it's just thet easy use a good pointy screw driver or a center punch but dont make the hole larger then 1/4 inch
a mechanic will carge you 250 to fix original drains and will likely do the same as i said a couple of wacks near the lower center on the floor boards
so get in place feet on floor slide them back against the seat with it all the way back now place pointy object between feet and wach it with a hammer
once through push pointy objest forward to create new drain

Water on front and rear passenger floor board, a lot of water

you can test again the car by putting a garden hose at the front of the windshield where it is supposed to **** fresh air. if you have a rusted part there and water could sipped in.

another option would be the recycle door of the airconditioning could be partly open ang letting the water come inside the car..

tnx 4 using fixya,
