The purpose of the operational check is to confirm that the system operates properly.
CHECKING BLOWER
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.

Front Blower Motor Diagno-
sis Procedure".
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 XXXX DISCHARGE
AIR FLOW.
If NG, go to trouble diagnosis procedure for HAC-16, "
Mode Door Diagnostic Procedure".
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 XXXX 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 XXXX 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 XXXX 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 XXXX MAG CLUTCH CIR.
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.
2. Turn mode dial to ( ) DEF.
3. Confirm that the compressor clutch engages (sound or visual inspection). Conditions : Engine running at normal operating temperature
