03 Toyota 4-Runner A/C

airconditioning

#1

This vehicle has passenger side air control. The A/C blows cold for the passenger vents, and warm for the drivers vents. The mode door actuator works properly. What would you suggest to fix this?


#2

How is the zoning done? If it uses dampers, a damper could be stuck. If it uses solenoid refrigerant valves, a valve might be stuck closed. In either case, the control circuit might have a fault.
Is there only one evaporator coil or are there two? That makes a big difference in the way the system is designed.
