Climate Control Unit Inspection: Notes

Remove the climate control unit with the connector connected. (See CLIMATE CONTROL UNIT REMOVAL/INSTALLATION [FULL-AUTO AIR CONDITIONER] .)
Switch the ignition ON (engine off or on).
Connect the negative (-) lead of the tester to body ground.
Insert the positive (+) lead of the tester into each climate control unit terminal and measure the voltage according to the terminal voltage table.
- If there is any malfunction, inspect the parts under "Inspection item (s)".
  - If the parts under "Inspection item (s)" are found to be normal (except for terminal 1E), replace the climate control unit.
  - For terminal 1E, first try replacing the blower fan controller. If there is still any malfunction, replace the climate control unit.
