When the air outside is cold, DON'T use recirculate. Even cold foggy
outside air is dryer than the warm inside air and letting outside air
come in will eliminate the fogging problem.
When the outside air is not cold, you must use the AC when the defrost
is on. This is normal. The AC will dehumidify the air.

This can be caused by shutting the car off with the AC on. Volvo's
solution on newer models is to have the AC/heater fan kick on after the
water has drained out of the AC housing. They do have sprays they can
use to eliminate the smell. They are anti-fungal sprays.

This is also a problem. You usually get water on the passenger floor
mat and sometimes the passengers legs when the drain is plugged. Usually
the dealer can put it on a lift and clear it in a couple seconds. I
haven't figured out where it is.
