Hey there, I own a 99' Dodge Intrepid, 87k miles, just discovering a large puddle of water, noted several times on the drivers side floorboard, and remains damp after I dry it up. I origianlly thouth it was the heater core, but after speaking with a good friend, who mentioned he had to replace door framing gaskets? I'm hoping it is not coolant on the drivers side floor board. I ordered a new heater core, thinking I'd replace that? Could it be a leak from somewhere else? I can't see anything, and have used a flashlight etc...it's touch and go with the water accumulation. What do you think it could be?

 

does it only happen after a rain?

 

You know, it was after a big snow, a couple of times. Haven't seen it sense, and sent back the heater core I ordered. I think it may be the seals, but not sure where, door, windows etc.???

 

have someone in the car with the doors closed and spray water all over the window and door area and see if they can see a leak. this may take a while but it does work a sprayer works good, as does a light pressure washer (dont get to close tho you dont want to damage the paint or seals)
