In my car the outside air vent is not closing completley. At least that is what it
seems like when driving. I can feel the air come throught the vents in the car when the ventelation system is off. Any ideas why these vents are not completly shut off. I seems like when I run the a/c I am getting a mixture of outside air and the a/c therfore the air is not as cold as it should be.
