why is water leaking on passenger side floor daily?

Make sure it is not antifreeze- it will be oily and not dry quickly. If is just water check for plugged cowling drains. Greg

you might want to check to see if water is coming in from the heater coil area had the same problem but was working on ac @ the time. there is a drainage right up under the coil if it get clogged up it will back up
