Follow the table below to check the defogger relay for continuity. DEFOGGER RELAY CONTINUITY
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?
YES:
Go to Step 5.
NO:
Repair or replace the connector. Refer to

STEP 5. Measure the voltage at defogger connector F-01.
1. Disconnect defogger connector F-01, and measure the voltage at the
harness side.
2. Turn the ignition switch to the "ON" position.
3. Turn the defo
gger switch to the "ON"
position.

4. Measure the voltage between terminal 1 and ground.
The measured value should be approximately 12 volts (battery
positive voltage).
Q: Is the measured voltage approximately 12 volts?
YES:
Go to Step 13 .
NO:
Go to Ste
