Q: Is the wiring harness between power window relay 

connector C-203 (terminal 4) and front power window 
sub switch connector E-12 (terminal 6) in good 
condition?
YES : 
No action is necessary and testing is complete.
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 
front power window sub switch is operated, the front 
power window (LH) should raise and lower normally.

STEP 11. Check the ground circuit to the front power 
window sub switch. Measure the resistance at front power 
window sub switch connector E-12.
(1) Disconnect front power window sub switch connector E-12 

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 13.
NO :  Go to Step 12.

STEP 12. Check the wiring harness between power 
window main switch connector E-04 (terminals 7 and 9) 
and front power window sub switch connector E-12 
(terminals 8 and 5).

NOTE: Also check intermediate connectors C-12 and C-26. If 
intermediate connector C-12 or C-26 is damaged, 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-04 (terminals 7 and 9) and front 
power window sub switch connector E-12 (terminals 8 
and 5) in good condition?
YES : 
Replace the power window main switch. When the 

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

STEP 13. Check the wiring harness between front power 
window sub switch connector E-12 (terminals 4 and 7) and 
front power window regulator motor (LH) connector E-13 
(terminals 1 and 2).
Q: Is the wiring harness between front power window sub 

switch connector E-12 (terminals 4 and 7) and front 
power window regulator motor (LH) connector E-13 
(terminals 1 and 2) in good condition?
YES : 
No action is necessary and testing is complete.
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 
front power window sub switch (LH) is operated, the 
front power window (LH) should raise and lower 
normally.

STEP 14. Check rear power window sub switch (LH) 
connector E-17 and rear power window regulator motor 
(LH) connector E-16 for loose, corroded or damaged 
terminals, or terminals pushed back in the connector.
Q: Are rear power window sub switch (LH) connector E-17 

and rear power window regulator motor (LH) connector 
E-16 in good condition?
YES : 
Go to Step 15.
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 

(LH) is operated, the rear power window (LH) should 
raise and lower normally.

STEP 15. Check the rear power window sub switch (LH) for 
continuity.
(1) Remove the rear power window sub switch (LH). Refer to 

GROUP 42, Door, Door Glass and Regulato

P.42-39

.

(2) Check continuity when the rear power window sub switch 

(LH) is operated to "UP" or "DOWN" position.

Q: Is the rear power window sub switch (LH) normal?

YES : Go to Step 16.
NO :  Replace the rear power window sub switch (LH). 

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

STEP 16. Check the rear power window regulator motor 
(LH).
(1) Remove the rear power window regulator assembly (LH). 

Refer to GROUP 42, Door, Door Glass and Regulator 

P.42-39

.

(2) Connect a battery to the motor terminal, and check that the 

motor runs freely.

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

YES : Go to Step 17.
NO :  Replace the rear power regulator assembly (LH). 

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

STEP 17. Check the battery power supply circuit to the rear 
power window sub switch (LH). Measure the voltage at rear 
power window sub switch (LH) connector E-17.
(1) Disconnect rear power window sub switch (LH) connector 

E-17 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 20.
NO :  Go to Step 18.
