HFC-134a (R-134a) Service Tool and EquipmentINFOID:0000000005930833
Never mix HFC-134a refrigerant and/or its specified oil with CFC-12 (R-12) refrigerant and/or its oil.
Separate and non-interchangeable service equipment must be used for handling each type of refrigerant/oil.
Refrigerant container fittings, service hose fittings and service equipment fittings (equipment which handles
refrigerant and/or oil) are different between CFC-12 (R-12) and HFC-134a (R-134a). This is to avoid mixed
use of the refrigerants/oil.
Adapters that convert one size fitting to another must never be used refrigerant/oil contamination will occur
and compressor failure will result.

TROUBLE DIAGNOSIS
1. Turn blower control dial clockwise to "1" position. Blower should operate on low speed.
2. Turn blower control dial clockwise to "2" position, and continue checking blower speed until all speeds are
checked.
3. Leave blower on Maximum speed.
If NG, go to trouble diagnosis procedure for MTC-34, "
Front Blower Motor Circuit".
If OK, continue the check.
CHECKING DISCHARGE AIR
1. Turn mode door control dial to each position.
2. Confirm that discharge air comes out according to the air distribution table. Refer to MTC-20, "
Discharge
Air Flow".
If NG, go to trouble diagnosis procedure for MTC-32, "
Mode Door".
If OK, continue the check.
CHECKING RECIRCULATION
1. Set intake door lever to REC position.
2. Operate intake door lever to FRE position.
3. Listen for intake door position change (you should hear blower sound change slightly).
If NG, go to trouble diagnosis procedure for MTC-34, "
Intake Door".
If OK, continue the check.
CHECKING TEMPERATURE DECREASE
1. Turn temperature control dial counterclockwise to full cold position.
2. Check for cold air at discharge air outlets.
If NG, go to trouble diagnosis procedure for MTC-46, "
Insufficient Cooling".
If OK, continue the check.
CHECKING TEMPERATURE INCREASE
1. Turn temperature control dial clockwise to full hot position.
2. Check for hot air at discharge air outlets.
If NG, go to trouble diagnosis procedure for MTC-53, "
Insufficient Heating".
If OK, continue the check.
CHECKING A/C SWITCH (IF EQUIPPED)
1. Turn fan control dial to the desired (1 to 4 speed) position.
2. Press A/C switch.
3. A/C switch indicator will turn ON.
• Confirm that the compressor clutch engages (sound or visual inspection).
If NG, go to trouble diagnosis procedure for MTC-38, "
Magnet Clutch Circuit (If Equipped)".
If OK, continue the check.
CHECKING DEFROST A/C SWITCH (IF EQUIPPED)
1. Turn fan control dial to the desired (1 to 4 speed) position.
