2002, 4.7 liter, 4x4

The problem is that only hot air blows from the drivers side vents, not the passenger side. Additionally, when driving at highway speeds I can hear the road noise through the right side vents. The sound is similar to if your door is not closed all of the way.

Any help would be greatly appreciated...

Thanks.

 

Sounds to me you have blend door issues. It's a PITA but doable. Do a search in the DIY section located on the first page of the forum.
