(3) Measure the voltage between terminal 1 and
earth.
OK: System voltage
Q: Is the check result normal?
YES :
Go to Step 10.
NO :
Go to Step 8.
STEP 8. Connector check: C-207 blower relay
connector
Q: Is the check result normal?
YES :
Go to Step 9.
NO :
Repair the connector.
STEP 9. Check the wiring harness between C-207
blower relay connector terminal No.1 and the
