Musty odor comes from vent when recirculating air. No smell with heat or AC.

Smells like coolant is coming from the air vents when I run the heater or defroster. Your eyes burn and you get a headache. Also my windows smog up and it takes a while to clear.
musty stale smell from the vents when A/C is on, especialy when on re-circ.
musty odor when air is on for 2 years. Now it blows only hot air from the passengers side when the air is on.

Musty smell from the HVAC system
bought the car in march, 2010 with 14000 miles on it and have always noticed a musty smell coming from the vents mostly when using the a/c. now the car has 44000 miles on it and the front passenger side floor board has been wet the last few times i have driven it in the rain.i have checked the cabin filter under the hood and was damp,looks like water could very easily come in through this vent, but havent yet proved it.
