Q: Is the wiring harness between outside/inside air selection damper
control motor connector C-106 (terminal 1) and the ignition switch (IG2)
in good condition?

YES:
It can be assumed that this malfunction is intermittent. Refer to
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 intermediate connector C-103, junction
block connector C-211 or C-215 is damaged, repair or
replace the connector as described in HARNESS
CONNECTOR INSPECTION

Q: Is the wiring harness between front blower relay connector C-202
(terminal 1) and the ignition switch (IG2) in good condition?

YES:
The front blower motor should operate normally.
NO:
Repair the wiring harness. The front blower motor should operate
normally.
STEP 7. Measure the voltage at front blower relay connector C-202.

1. Disconnect front blower relay connector C-202, and measure the voltage
at the junction block side.
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

2. Turn the ignition switch to the "ON" position.
3. Check if the DTC is set.
4. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the check result satisfactory?

YES:
Go to Step 2.
NO:
Refer to
DIAGNOSTIC TROUBLE CODE CHART
.
STEP 2. Check the refrigerant level.

Use the refrigerant recovery station to remove all of the refrigerant, and then
calculate the amount of the refrigerant and charge it.
Q: Is the refrigerant level correct?

YES:
Replace the A/C-ECU.
NO:
Correct the refrigerant level (Refer to
REFRIGERANT LEAK
REPAIR PROCEDURE
). Check that the air conditioning works
normally.
