Q: Is the wiring harness between A/C compressor clutch relay connector
B-16X (terminal 4) and A/C-ECU connector C-16 (terminal 10) in good
condition?
YES:
It can be assumed that this malfunction is intermittent.
NOTE: Also check intermediate connectors A-13 and C-24 for
loose, corroded, or damaged terminals, or terminals
pushed back in the connector. If intermediate connector
A-13 or C-24 is damaged, repair or replace the
connector as described in HARNESS CONNECTOR
INSPECTION
.

The measured value should be approx. 12 volts (battery positive
voltage).
Q: Is the measured voltage approx. 12 volts?
YES:
Go to Step 11 .
NO:
Go to Step 3.
STEP 3. Check front blower relay connector C-202 for loose, corroded or
damaged terminals, or terminals pushed back in the connector.

Q: Is front blower relay connector C-202 in good condition?
YES:
Go to Step 4.
NO:
Repair or replace the connector. Refer to
HARNESS
CONNECTOR INSPECTION
. The blower motor should operate
normally.

Q: Is the front blower relay continuity in good condition?
YES:
Go to Step 5.
NO:
Replace the front blower relay. The front blower motor should
operate normally.
STEP 5. 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.
2. Turn the i
gnition switch to the "ON"
position.
