STEP 5. Check front power window sub switch connector
E-12 and front power window regulator motor (LH)
connector E-13 for loose, corroded or damaged terminals,
or terminals pushed back in the connector.
Q: Are front power window sub switch connector E-12 and
front power window regulator motor (LH) connector
E-13 in good condition?
YES : Go to Step 6.
NO : Repair or replace the damaged component(s). Refer
to GROUP 00E, Harness Connector Inspection
. When the front power window sub switch
(LH) is operated, the front power window (LH) should
raise and lower normally.
STEP 6. Check the front power window sub switch for
continuity.
(1) Remove the front power window sub switch. Refer to
GROUP 42, Door, Door Glass and Regulator
.
(2) Check continuity when the front power window sub switch is
operated to "UP" or "DOWN" position.
Q: Is the front power window sub switch normal?
YES : Go to Step 7.
NO : Replace the front power window sub switch. When
the front power window sub switch is operated, the
front power window should raise and lower normally.

STEP 7. Check the front power window regulator motor
(LH).
(1) Remove the front power regulator assembly (LH). Refer to
GROUP 42, Door, Door Glass and Regulator
.
(2) Connect a battery to the motor terminal, and check that the
motor runs freely.
Q: Is the front power window regulator motor (LH) normal?
YES : Go to Step 8.
NO : Replace the front power regulator assembly (LH).
When the front power window sub switch (LH) is
operated, the front power window (LH) should raise
and lower normally.
STEP 8. Check the battery power supply circuit to the front
power window sub switch. Measure the voltage at front
power window sub switch connector E-12.
(1) Disconnect front power window sub switch connector E-12
and measure the voltage available at the wiring harness
side of the connector.
(2) Measure the voltage between terminal 6 and ground.
• The voltage should measure approximately 12 volts
(battery positive voltage).
Q: Is the measured voltage approximately 12 volts (battery
positive voltage)?
YES : Go to Step 11.
NO : Go to Step 9.
