2004 MITSUBISHI ENDEAVOR Battery terminals

Q: Is the wiring harness between front blower motor connector C-111
(terminal 1) and front blower relay connector C-202 (terminal 4) in good
condition?

YES:
The front blower motor should operate normally.
NO:
Repair the wiring harness. The front blower motor should operate
normally.
STEP 11. Check the front blower fan and motor operation.

When battery voltage is applied between the terminals, check that the motor
operates. Also, check that there is no abnormal noise.
Q: Is there any abnormal noise?

YES:
Go to Step 12.
NO:
Replace the front blower relay. The front blower motor should
o
perate 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
.

Follow the table below to check the defogger relay for continuity. DEFOGGER RELAY CONTINUITY

Q: Is the defogger relay in good condition?

YES:
Go to Step 4.
NO:
Replace the defogger relay. The defogger system should work
normally.
STEP 4. Check defogger connector F-01 for loose, corroded or damaged
terminals, or terminals pushed back in the connector.

Q: Is defogger connector F-01 in good condition?

Q: Is the wiring harness between A/C-ECU connector C-16 (terminal 3)
and the battery in good condition?

YES:
It can be assumed that this malfunction is intermittent.
NOTE: Also check joint connector C-04 and intermediate
connector C-31 for loose, corroded, or damaged
terminals, or terminals pushed back in the connector. If
joint connector C-04 or intermediate connector C-31 is
damaged, repair or replace the connector as described
in HARNESS CONNECTOR INSPECTION

POTENTIOMETER CHECK While checking the air mix damper control motor, measure the resistances between
terminals numbers 3 and 5 and between numbers 3 and 7. At this time, the
resistances should change gradually within the standard value.
Standard value: 1.7 (MAX HOT) - 5.0 (MAX COOL) kohm MODE SELECTION DAMPER CONTROL MOTOR CHECK Check the mode selection dam
per control motor b
