DIAGNOSIS
STEP 1. Check the defogger and A/C operations.
Q: Do the defogger and A/C work normally?
YES :
Go to Step 2.
NO : Refer to Inspection procedure 9
"Malfunction of the A/C-ECU power supply
system P.55-53 ."
NO : Refer to Inspection procedure 10
"Malfunction of the A/C-ECU power supply
system P.55-56 ."
STEP 2. Connector check: C-107 outside/inside
air selection damper control motor connector
Q: Is the check result normal?
YES :
Go to Step 3.
NO : Repair the connector.
STEP 3. Voltage measurement at the C-107
outside/inside air selection damper control motor
connector.
(1) Disconnect the connector, and measure at the
wiring harness side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal 7 and
body earth.
OK: System voltage
