High And Low Pressure Sides Are Equal, Or High-Pressure Side Is Low

1. CHECK REFRIGERANT LEAKS. 

   Check the refrigerant for leaks. Ref. to HVAC SYSTEM (HEATER, VENTILATOR AND A/C)>Refrigerant Leak Check>INSPECTION .

   NOTE: When high-pressure side is less than 0.69 MPa: Go to step  2.

   Are there refrigerant leaks?

   • Yes  : Repair the refrigerant leaking points.
   • No  : Go to  2.
2. FILL PROPER AMOUNT OF REFRIGERANT. 

Drain all refrigerant, and refill proper amount of refrigerant.

• Recovery: Ref. to HVAC SYSTEM (HEATER, VENTILATOR AND A/C)>Refrigerant Recovery Procedure>PROCEDURE .
• Fill: Ref. to HVAC SYSTEM (HEATER, VENTILATOR AND A/C)>Refrigerant Charging Procedure>PROCEDURE .

Is refrigerant pressure within the standard value?

• Yes  : Refrigerant pressure is normal.
• No  : Inspect the compressor. Ref. to AIR CONDITIONER (DIAGNOSTICS)>Diagnostics with Phenomenon>INSPECTION>COLD AIR DOES NOT COME OUT EVEN WHEN THE A/C SWITCH IS PRESSED . THE GLASS CANNOT BE DEFOGGED. (COMPRESSOR DOES NOT OPERATE.).
