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 19. Check the ground circuit to the rear power 
window sub switch (LH). Measure the resistance at rear 
power window sub switch (LH) connector E-25.
(1) Disconnect rear power window sub switch (LH) connector 

E-25 and measure the resistance available at the wiring 
harness side of the connector.

(2) Measure the resistance value between terminal 5 and 

ground, and also between terminal 8 and ground.

• The resistance should be 2 ohms or less.

Q: Is the measured resistance 2 ohms or less?

YES : Go to Step 21.
NO :  Go to Step 20.

window main switch connector E-19 (terminals 18, 19) and 
rear power window sub switch (LH) connector E-25 
(terminals 5, 8).

• Check the power supply lines for open circuit and short cir-

cuit.

NOTE: Also check intermediate connectors C-32, C-126 and 
D-21. If intermediate connector C-32, C-126 or D-21 is dam-
aged, repair or replace the damaged component(s) as 
described in GROUP 00E, Harness Connector Inspection 

P.00E-2

.

Q: Is the wiring harness between power window main 

switch connector E-19 (terminals 18, 19) and rear power 
window sub switch (LH) connector E-25 (terminals 5, 8) 
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.

STEP 21. Check the wiring harness between rear power 
window sub switch (LH) connector E-25 (terminals 4, 7) 
and rear power window motor (LH) connector E-26 
(terminals 4, 1).

• Check the power supply line for open circuit and short cir-

cuit.

Q: Is the wiring harness between rear power window sub 

switch (LH) connector E-25 (terminals 4, 7) and rear 
power window motor (LH) connector E-26 (terminals 4, 
1) 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.

STEP 22. Check rear power window sub switch (RH) 
connector E-11 and rear power window motor (RH) 
connector E-12 for loose, corroded or damaged terminals, 
or terminals pushed back in the connector.
Q: Are rear power window sub switch (RH) connector E-11 

and rear power window motor (RH) connector E-12 in 
good condition?
YES : Go to Step 23.
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 23. Check the rear power window sub switch (RH) for 
continuity.
(1) Remove the rear power window sub switch (RH). Refer to 

GROUP 42A, Door, Door Glass and Regulator 

P.42A-148

.

(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 24.
NO :  Replace the rear power window sub switch (RH). 

When the rear power window sub switch (RH) is 
operated, the rear power window (RH) should raise 
and lower normally.

motor runs freely.

Q: Is the rear power window motor (RH) normal?

YES : Go to Step 25.
NO :  Replace the rear power window motor (RH). When 

the rear power window sub switch (RH) is operated, 
the rear power window (RH) should raise and lower 
normally.

STEP 25. Check the battery power supply circuit to the rear 
power window sub switch (RH). Measure the voltage at 
rear power window sub switch (RH) connector E-11.
