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
