Q: Is the wiring harness between defogger relay connector C-201
(terminal 5) and the fusible link (1) in good condition?
YES:
Check that the defogger system works normally.
NO:
Repair the wiring harness. Check that the defogger system works
normally.
STEP 8. Measure the voltage at defogger relay connector C-201.
1. Disconnect defogger relay connector C-201, and measure the voltage at
the junction block side.
2. Turn the i
gnition switch to the "ON"
position.
NOTE: Also check junction block connector C-216 for loose,
corroded, or damaged terminals, or terminals pushed
back in the connector. If junction block connector C-216
is damaged, repair or replace the connector as
described in HARNESS CONNECTOR INSPECTION
