I have a 2003 Saturn ION-3. I noticed that when I am using the front vents
or heater vents that some air (not much) comes from the defrost vents. When
humid outside and I am using my A/C there tends to form moisture on the
windshield on the outside of the car. I didn't notice that last year.

The question: is a little air suppose to come out of the defrost vents when
the vents are set for the front vents or heater? I asked the dealership and
they said yes.

Thank you
Mark
