CLIMATE CONTROL UNIT INSPECTION [FULL-AUTO AIR CONDITIONER]
1. Turn the ignition switch to the ON position.
2. Connect the negative (-) lead of the tester to body ground.
3. By inserting the positive (+) lead of the tester into each climate control unit terminal, measure the voltage according to the terminal voltage table.
- If there is any malfunction, inspect the parts under "Inspection item (s)".

- For terminal F first try replacing the power MOS FET. If there is still any malfunction, replace the climate control unit.
