Problem should be the blend door actuators. Check the passenger blend door for proper operations.
IF there is heat in one area, that tells me there is an issue with the blend air door. The doors determine if you get heat or AC. If you have dual climate control, you have two blend doors. One is stuck or not operating. They are located near the heater core.
