2003 Sebring LXi 3.0l coupe blows cold air out driver side while blowing warm air out passenger side. I have flushed the cooling system, replaced the radiator cap, and removed the air directional vents to examine the plenum for obstructions. None found. This problem exists in the defroster vent as well. Any suggestions?

 

I have the same car and same problem. What did you do to fix it? Mine is half in pieces but the only problem I could find was the drivers side top of the evaporator heat exchanger was covered with dirt.
