i drive for about 45 minutes or more a puddle builds up on the passenger side floor in the little dip. Its not wet where the floor meets the back of the dash, just by the seat so its not comin from above. Any clue where it could be coming from? Its jusy water.

 

Heater core

 

Not if it is water and not coolant.


Might be the a/c drain that is clogged (if you are using a/c at the time).

Whats the best way to unclog the drain?

 

Poke something up in there to open it up.
