Does your windshield get steamed up on the inside once the car has warmed up, and not clear, get worse, when you run the heater? If so, that's your heater core. I think there are 2 in these cars. One for each side. If not then it's the weather stripping for your carbon air filter. Also, if it is your heater core you will smell coolant in the car.

Sounds like either the A/C evaporator drain elbow is clogged, or the air inlet grille panel (cabin air filter cover) may be leaking and passing through the heater blower. Both easy fixes. There is a modification you do to the air grille by replacing the original one with one from a Grand Prix. Can be found under "Permanent Cabin Air filter Cover Fix".
