Inspection 1. Turn the ignition switch OFF. 2. Disconnect the HO2S connector. 3. Measure resistance between the HO2S terminals 1 and 2. 4.
Description The compressor is the power unit of the A/C system. It is located on the side of engine block and driven by a V-belt of the engine. The compressor changes low-pressure and low-temperature refrigerant gas into high-pressure and high-temperature refrigerant gas.
Inspection 1. Turn the ignition switch OFF. 2. Disconnect the mode control actuator connector. 3. Verify that the mode control actuator operates to the defrost mode when connecting 12V to terminal 3 and grounding terminal 4. Verify that the mode control actuator operates to the vent mode when connected in reverse.
