.
Q: Is the wiring harness between defogger relay connector C-201
(terminal 1) and ignition switch (IG2) in good condition?

YES:
Check that the defogger system works normally.
NO:
Repair the wiring harness. Check that the defogger system works
normally.
STEP 10. Check A/C-ECU connector C-16 for loose, corroded or dama
ged
terminals, or terminals pushed back in the connector.

Q: Is A/C-ECU connector C-16 in good condition?

YES:
Go to Step 11.
NO:
Repair or replace the connector. Refer to
HARNESS
CONNECTOR INSPECTION
. Check that the defogger system works
normall
y.
NOTE: Also check junction block connector C-215 for loose,
corroded, or damaged terminals, or terminals pushed
back in the connector. If junction block connector C-215
is damaged, repair or replace the connector as
described in HARNESS CONNECTOR INSPECTION
.

Q: Is the wiring harness between A/C-ECU connector C-17 (terminal 28)
and the ignition switch (IG2) in good condition?

YES:
It can be assumed that this malfunction is intermittent.
NOTE: Also check joint connector C-103, junction block
connectors C-211 and C-215 for loose, corroded, or
damaged terminals, or terminals pushed back in the
connector. If joint connector C-103, junction block
connector C-211 or C-215 is damaged, repair or replace
the connector as described in HARNESS CONNECTOR
INSPECTION
.
