A) Set the idle speed to 1000 rpm.
b) Fully open the doors.
2. Air conditioning mode.
A) Set the heater fan speed to high.
b) Turn on the air conditioner.
V) Move the air intake damper to position "RECIRC".
G) Set the maximum cooling mode.
3. Check the amount of refrigerant by the presence of bubbles in the service window of the receiver.
A) If bubbles are visible in the service window (lack of refrigerant), then check for leaks in the system and top up the system to the correct level.
Note: See section on refrigerant quantity "Charging system".
b) If bubbles are not visible (the amount of refrigerant is normal, or the system is recharged, or there is no refrigerant), then the method of elimination - see the subparagraphs "V" And "G".
V) If there is no temperature difference between the compressor inlet and outlet (No refrigerant or minimum amount of refrigerant), check for refrigerant leaks, then recharge the system to normal.
G) If there is a large temperature difference between the inlet and outlet of the compressor (the amount of refrigerant is normal or the system is recharged), then the method of elimination - see subparagraphs "d" And "e".
d) If the refrigerant in the service window becomes transparent immediately after turning on the air conditioner (system recharge), then evacuate and charge the system to capacity.
e) If, after turning on the air conditioner, the refrigerant foams and then becomes transparent, then the amount of refrigerant is normal.
