You will probably need a new RF temperature actuator which is on top of your HVAC box/under dash pad.($400 + at dealership.) I have replaced MANY....They get stuck and dont know where they are...If you want to try and recalibrate them yourself you can remove the HVAC/ECAS fuse in the underhood fuse block for 30 seconds(engine running) and reinstall the fuse and wait(IMPORTANT) 2 minutes...do not operate the a/c controls during this time...(engine still running) ..Then shut off vehicle and wait 30 seconds.. start the engine again and operate the A/C and see what happens....Hope this helps!!

Did you check your coolant level or was it low and you added to it at some point? If so the system my need to be bleed or worst case the thermostat is going bad.

with a dual climate control system, it is imperative for a proper refrigerant charge to be maintained. the symptom you describe is a possible indicator of low charge on the system. the ac evaporator core is closest to the right side of vehicle thereby making air feel cooler on that side, on the left side of the vehicle the cooled air has farther to travel and warms up from cabin air before it discharged from the vents. this is the most probable issue for your vehicle...however if the charge is accurate, the issue would be more so in the air temperature doors which is located deep inside the dash...i hope this helps...good luck!

Its more then likely the temp door broken or temp door motor broken/stuck. There is 2-3 of these motors under the dash on the side of the evap/heater core box. Some require extensive labor to replace, good luck
