Inspection 1. Disconnect the negative (-) battery terminal. 2. Open the sunglass case cover from the overhead console and remove the 2 screws holding the overhead console.
Oil Specification 1. The HFC-134a system requires synthetic (PAG) compressor oil whereas the R-12 system requires mineral compressor oil. The two oils must never be mixed. 2. Compressor (PAG) oil varies according to compressor model. Be sure to use oil specified for the compressor model.
Inspection 1. Turn the ignition switch OFF. 2. Disconnect the intake actuator connector. 3. Verify that the intake actuator operates to the fresh position when connecting 12V to terminal 3 and grounding terminal 4. Verify that the intake actuator operates to the recirculation position when connected in reverse.
