Water leakage on passenger side door - SWISHING SOUND ON PASSENGER SIDE?

Answer 1

Water or coolant? Taste the water and if it is sweet it is coolant and your heater core is leaking and needs replacing. It is is just water, suspect a stopped up cowl drain line or a leaking windshield. Now if you just have water trapped inside the door, the drain holes in the door are plugged. Look on the bottom underside of the door and you will see drain ports. Clean them out with a piece of stiff wire. Check all your other doors to make sure they are not partially clogged.
