The manual climate control systems (C42 & C60) use the following five actuators in order to adjust the temperature and the air distribution:
| • | The electric actuator or the temperature actuator controls the temperature valve. |
| • | The air inlet actuator controls the air inlet valve. |
| • | The slave actuator controls the heater slave valve. |
| • | The mode actuator controls the mode valve. |
| • | The defroster actuator controls the defroster valve. |
When servicing an actuator, replace parts with the correct service parts for the actuator being serviced. The electric actuators for the manual climate control systems (C42 & C60) have a red R on the top in order to differentiate the electric actuators from the electric actuator used on the automatic climate control system (C68).
The air inlet actuator and the slave actuator are vacuum motors with one vacuum port in order to move the attached valves in one direction.
The mode actuator and the defroster actuator are vacuum motors with two vacuum ports in order to move the attached valves in two directions.
