Answer 1

it could be leaking in through the ac fresh air filter box underneath the cowl. just run water from the upper windshield area and let it run down the windshield and look to see if it is dripping in from the outside. if so then remove your windshield wiper arms and remove the cowl. you should be able to follow the water trail and find the leak and reseal it.

Answer 2

Is your car using coolant,do you have to add coolant often?Is there steam coming out of defroster vents?If so,your heater core or hoses to heater core are leaking.

You should check rubber door seals around your doors.They break down or get worn over the years and can leak.To check whether you wind shield is leaking,have some one hold a garden hose on it while you look for water dripping under dash.
