Question AC blows cold air only in driver side vents

My 2003 RX-300 ac blows cold air out of driver's side vents. It seems that the air blowing out of the passenger side is mixing with outside air because it is not as cold as in the driver's side, eventhough the recirculation buttom is on.

What could this be?

Sounds like the air mix servos are going bad. It's quite a common thing around here and many posts about it. Look around. There's a plethora of information here. I replaced both of mine and work like a charm.
