Title says it all. The air comes out nice and cold, but only from the defrost vent and floor. My commute home from work is about an hour in stand still traffic not to mention the Texas heat. Any advice will help.

sounds like the vent selector is not working - you have electronic climate control, right?

it may also be a funky head unit - when you change vent settings, do you hear anything that clicks?

No nothing clicks. It just keeps coming from defrost/floor.

a tech 2 scanner may be able to command the vent selection door open/closed - then that would narrow it down to the head unit - if it cant, then the vent selector motor/wiring is bad.

you may also try a working good head to test also.
