INSPECT PIPING CONNECTIONS FOR LOOSE
• Are piping connections loose?
Yes
Tighten connections to specified torque. If the
vane makes a noise, add 10 ml {10 cc,
0.338 fl oz} of compressor oil to the A/C
compressor. Verify that the noise is no longer
heard. Adjust refrigerant to specified amount, then
go to Step 21.
No
If the vane makes a noise, add 10 ml {10 cc,
0.338 fl oz} of compressor oil to the A/C
compressor. Verify that the noise is no longer
heard.
Replace O-ring on piping, adjust refrigerant to
specified amount, then go to Step 21.
14
CHECK TO SEE WHETHER MALFUNCTION IS
IN EXPANSION VALVE, AIR MIX ACTUATOR
AND COMPRESSOR OIL OR ELSEWHERE
• Does refrigerant high-pressure value hardly
increase?
Yes
Go to next step. (Pressure hardly increases.)
No
Go to Step 17.
15
CHECK TO SEE WHETHER PROBLEM IS IN
COMPRESSOR OIL AMOUNT AND A/C
COMPRESSOR OR ELSEWHERE
• When engine is racing, does high-pressure
value increase?
Yes
Return to Step 3.
No
Go to next step.
16
CHECK TO SEE WHETHER PROBLEM IS IN
COMPRESSOR OIL AMOUNT OR A/C
COMPRESSOR
• After compressor oil is replenished each 10 ml
{10
cc,
0.338 fl oz}, does high-pressure value
increase?
Yes
Troubleshooting completed. (Explain to customer
that cause was insufficient compressor oil.)
No
Replace A/C compressor, then go to Step 21.
(Cause is defective A/C compressor.)
17
CHECK TO SEE WHETHER MALFUNCTION IS
IN EXPANSION VALVE OR ELSEWHERE
• Is only refrigerant low-pressure value high?
Yes
Go to Step 20.
No
Go to next step.
18
VERIFY THAT AIR MIX ACTUATOR IS
INSTALLED SECURELY AND PROPERLY
• Are heater unit air mix links, air mix cranks,
and air mix rods securely and properly
installed?
Yes
Go to next step.
No
Repair or install links, cranks, and rods securely
in proper position, then go to Step 21.
19
ADJUST COMPRESSOR OIL
• Set the fan control lever at 4th position.
• Turn the A/C switch on.
• Set to FRESH mode.
• Set the temperature control to MAX COLD.
• Set to VENT mode.
• Run engine at a constant 1,500 rpm for 10
minutes.
• Run engine at idle speed for 1 minute.
• One engine speed cycle is defined as going
from idle speed to 4,000 rpm and back to idle
speed over a period of 12 seconds. Perform 5
cycles.
• Run engine at idle speed for 30 seconds.
• Remove all compressor oil from A/C
compressor and verify that it is 100 ml {100 cc,
3.38 fl oz}.
• If it is more than 100 ml {100 cc, 3.38 fl oz},
put only 100 ml {100 cc, 3.38 fl oz} back into
A/C compressor.
• Carry out above Steps 1 to 10 again and verify
that compressor oil is 100 ml {100 cc,
3.38 fl oz}.
• Is there 100 ml {100 cc, 3.38 fl oz} of
compressor oil in A/C compressor?
Yes
Go to Step 21.
No
Follow Steps 1 to 10 again until compressor oil is
100 ml {100 cc, 3.38 fl oz}.
