What Would Cause This?
 

Turned my AC on for the first time this year and both drivers side dash vents are blow cool air. Actually the round drivers side vent by the window isn't blowing cool at all. The passenger side dash vents are blowing COLD air.

Switch it to the floor and the drivers side is blowing cool air, the passenger side is blowing COLD air.

I will be taking it in to the dealer but was just curious if anyone could explain why this is happening.

I'm sorry pny. I'm not sure why this would happen. Keep us posted on what your dealer has to say. Hopefully they can straighten things out for you.
