water lakage in dash board

Leaves or debris must have blocked the drain tube which is preventing water to drain away. Clear leaves and debris from around the windscreen wiper panel then open the hood remove any plastic trim panels you can gain easily gain access to and clear leaves and debris. I looked in my information but can't get a clear picture of where the air conditioning/heater control box drain tube is but there is usually a tube low down on the firewall passenger side to allow condensation or water that may gather in the heater box to drain. You may only be able to gain access to this from under the car and may need to stick a small screwdriver or piece of coat hanger to dislodge debris stuck in the drain pipe.
