Floor wet on passenger side, a/c condensation dripping from under dash, why?
 

My 2003 Galant has developed a problem where a/c condensation is dripping down from somewhere under the dash on the passenger side, making the floor quite wet and mildewy. It's tied to the a/c system, definitely not the heater core/coolant. Is anyone familiar with this problem and what can be done to fix it?
Thanks!
