Q:Is the blower relay in good condition?
YES:
Go to Step 3.
NO:
Replace the rear window defogger relay.
STEP 3. Measure the voltage at blower relay connector
C-303.
(1)
Disconnect blower relay connector C-303, and measure the
voltage at the junction block side.
ZC6022230020
Harness side: C-303
(2)
Measure the voltage between terminals 1 and ground.
⦆
The measured value should be approximately 12 volts
(battery positive voltage).
(3)
Measure the voltage between terminals 4 and ground.
⦆
The measured value should be approximately 12 volts
(battery positive voltage).
Q:Is the measured voltage approximately 12 volts?
YES:
Go to Step 5.
NO:
Go to Step 4.

MANUAL A/C DIAGNOSIS
STEP 4. Check the wiring harness between blower relay
connector C-303 (terminals 1 and 4) and the fusible link (37).
Q:Is the wiring harness between blower relay connector
C-303 (terminals 1 and 4) and the fusible link (37) in good
condition?
YES:
It can be assumed that this malfunction is
intermittent. Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points - How to Cope
with Intermittent Malfunctions P.00-15.
NO:
Repair or replace the wiring harness. Refer to GROUP
00E, Harness Connector Inspection P.00E-2.
STEP 5. Check blower relay connector C-114 for loose,
corroded or damaged terminals, or terminals pushed back
in the connector.
Q:Is blower relay connector C-114 in good condition?
YES:
Go to Step 6.
NO:
Repair or replace the connector. Refer to GROUP 00E,
Harness Connector Inspection P.00E-2.
STEP 6. Check the wiring harness between blower relay
connector C-303 (terminal 3) and blower motor connector
C-114 (terminal 2).
Q:Is the wiring harness between blower relay connector
C-303 (terminal 3) and blower motor connector C-114
(terminal 2) in good condition?
YES:
It can be assumed that this malfunction is
intermittent. Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points - How to Cope
with Intermittent Malfunctions P.00-15.
NO:
Repair or replace the wiring harness. Refer to GROUP
00E, Harness Connector Inspection P.00E-2.
