Are you able to control the driver side air temperature at the dash registers? If not and you can control the passenger side of the dual climate system then you have an issue with the air temperature control door (moves between the heater core heated air and the AC evaporator cold air stream) deep inside the dash or the electric actuator that moves it or in most cases both.
Check the actuator motor on the heater it directs the air into the vents. There is probably two of them be sure to check both. The motor makes the vents move and again directs the air where you want. Hope this helps.
The actuator door that is behind the dash that closes off the heater core from shooting hot air thru the vents might be your problem. When you turn on your ac the actuator shuts the door to prevent the air from flowing thru the heater core into the cabin, this may be your problem if everything else is working properly. Let us know.
try this pull your ac heat control box out and unplug it leave unplugged for 2 minutes then plug back in this will reset the computer sounds like the computer is malfunctioning and this should take around 30 minutes to do and fix the problem it twhere you turn knobs to control heat ac fan speed and vent/defrost/settings hope this helps
assuming you have an electronic controlled (digital) dual zone system, it is most likely your heater blend door motor has failed, check and see which side is operating and buy the one you need and replace, it has 2 or 3 screws on the side, i think size is 4.5 mm or 5.5 mm and you have to take off lower plastic cover under dash and remove screws which go on horizontally... install heater door with temp swithched to the middle, move door to middle, if not you need to place new motor into plug before installing and turn temp to cold, then turn by hand the white blend door tube to match motor then install... make sure you turn off ignition when working,,,
Behind the glove box you will see the heater box. On top of the heater box you will see a set of wires going to a small controller box that has an arm on it. It is probably not working and you can only by them at the dealer. It is the dual climate controller and cost approx. $100.
