rear power window sub switch (LH) is operated, the
rear power window (LH) should raise and lower
normally.
NO : The wiring harness may be damaged or the
connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary. When the
rear power window sub switch (LH) is operated, the
rear power window (LH) should raise and lower
normally.
STEP 22. Check the wiring harness between rear power
window sub switch (LH) connector E-17 (terminals 4 and 7)
and rear power window regulator motor (LH) connector
E-16 (terminals 1 and 2).
Q: Is the wiring harness between rear power window sub
switch (LH) connector E-17 (terminals 4 and 7) and rear
power window regulator motor (LH) connector E-16
(terminals 1 and 2) in good condition?
YES : Replace the power window main switch. When the
rear power window sub switch (LH) is operated, the
rear power window (LH) should raise and lower
normally.
NO : The wiring harness may be damaged or the
connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary. When the
rear power window sub switch (LH) is operated, the
rear power window (LH) should raise and lower
normally.

connector E-06 and rear power window regulator motor
(RH) connector E-07 for loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Q: Are rear power window sub switch (RH) connector E-06
and rear power window regulator motor (RH) connector
E-07 in good condition?
YES : Go to Step 24.
NO : Repair or replace the damaged component(s). Refer
to GROUP 00E, Harness Connector Inspection
P.00E-2. When the rear power window sub switch
(RH) is operated, the rear power window (RH) should
raise and lower normally.
STEP 24. Check the rear power window sub switch (RH) for
continuity.
(1) Remove the rear power window sub switch (RH). Refer to
GROUP 42, Door, Door Glass and Regulator P.42-39.
(2) Check continuity when the rear power window sub switch
(RH) is operated to "UP" or "DOWN" position.
Q: Is the rear power window sub switch (RH) normal?
YES : Go to Step 25.
NO : Replace the rear power window sub switch (RH).
