With the A/C on the two drivers vents blow cold air, the 3 passanger vents blow very little and air coming out of these vents not cold. Any advice? or what to fix or what a dealer may charge to fix?? Thanks Tomm

Sounds like a blend door problem. Run a search for it and you should find ALOT of info on it...

Yup, sounds like a blend door issue, in fact my baby is at the dealership right now having them fixa blend door problem. My issue was slightly different in that you could turn the selector switch to anything (blowing on your feet for example) and it just keeps blowing out the top vents. When I called the dealership the svc. mgr. immediately said it was a blend door issue and that it's unfortunately fairly common on our trucks Thank goodness for warranty I guess....
