My 06 300 recently began to blow warm air on the passenger side and normal cool air on the driver side vents. It does not have dual climate controls and the vent selector changes from floor to dash to defrost normally. Is this a charge problem or a mechanical problem within the vent system? Thanks for any advice.

 

more then likely low freon

 

I have an 06 300 as well and we're experiencing similar issue. Our problem is when the a/c is on any setting we get nothing but heat coming out of the rear console vents. Thought if you had found a fix for yours it might help guide me to a fix for ours.
