Water leaking on passenger side of car?

Most likely it is the ac system getting rid of condensed cooled humid air. If your car is over heating and it is a antifreeze leak it will be either green or yellow or orange in color. Also it will have a sweet taste to it. If you were to taste it. If that is the case, check all the hoses then check the water pump. The pump has a hole on it that the seals fail, it will leak directly down the motor.
