My 2003 E500 blows warm air on left vent and cold air on right vent even when set to low temperature setting. I checked the left and right blend air actuators and they're working fine. What could be the problem?

Open the hood, turn on the A/C and feel the suction line (compressor to expansion valve). It it's cold, that means that the problem is inside (actuator). If not cold, it means the system is low in charge.
Could you elaborate on this?:
"I checked the left and right blend air actuators and they're working fine"
try disconnecting the battery for 5 minutes to re-sync the blend door temp control motors.
