Q: Is the refrigerant temperature switch operating properly?

YES:
Go to Step 19.
NO:
Replace the refrigerant temperature switch. Check that the air
conditioning works normally.
STEP 19. Check the air conditioning compressor clutch operation.

Connect the compressor connector terminal to the battery positive (+) terminal
and ground the battery's negative (-) terminal to the compressor unit. At that
time, the air conditioning compressor clutch should make a definite operating
sound.
Q: Can the sound (click) of the air conditioning compressor clutch
operation be heard?

YES:
Go to Step 20.
NO:
Replace the compressor magnet clutch. Check that the air
conditionin
g works normall

Q: Is the defogger relay in good condition?

YES:
Go to Step 4.
NO:
Replace the defogger relay. The defogger system should work
normally.
STEP 4. Check defogger connector F-01 for loose, corroded or damaged
terminals, or terminals pushed back in the connector.

Q: Is defogger connector F-01 in good condition?
