Inspection1. After disconnecting the vapor hose from the PCV valve, remove the PCV valve. 2. Reconnect the PCV valve to the vapor hose.3. Run the engine at idle, then put a finger over the open end of the PCV valve and make sure that intake manifold vacuum can be felt.
Replacement1.Disconnect the negative (-) battery terminal. 2.Remove the heater and blower assembly.(Refer to Heater - "Heater Unit") 3.Remove the evaporator core cover (A) after loosening the mounting screws.4.Pull out the evaporator temperature sensor (A) from the evaporator core.
Inspection1.Turn the ignition switch OFF.2.Disconnect the temperature control actuator connector.3.Verify that the temperature control actuator operates to the cool position when connecting 12V to terminal 3 and grounding terminal 7.Verify that the temperature control actuator operates to the warm position when connected in reverse.
