connector E-03 for loose, corroded or damaged terminals, 
or terminals pushed back in the connector.

Q: Are front power window sub switch connector E-04 and 

front power window regulator motor (RH) connector 
E-03 in good condition?
YES : Go to Step 6.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. When the front power window sub switch 

(RH) is operated, the front power window (RH) 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 

P.42-39

.

(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 
(RH).

(1) Remove the front power regulator assembly (RH). 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 front power window regulator motor (RH) normal?

YES : Go to Step 8.
NO :  Replace the front power regulator assembly (RH). 

When the front power window sub switch (RH) is 
operated, the front power window (RH) 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-04.

(1) Disconnect front power window sub switch connector E-04 

and measure the voltage available at the wiring harness 

side of the connector.

(2) Measure the voltage between terminal 7 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.

STEP 9. Check power window relay connector C-203 for 
loose, corroded or damaged terminals, or terminals 
pushed back in the connector.

Q: Is power window relay connector C-203 in good 

condition?
YES : Go to Step 10.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. When the front power window sub switch 

(RH) is operated, the front power window (RH) should 
raise and lower normally.

STEP 10. Check the wiring harness between power 
window relay connector C-203 (terminal 4) and front power 

window sub switch connector E-04 (terminal 7).

NOTE: Also check junction block connector C-215 and inter-
mediate connector C-12. If junction block connector C-215 or 
intermediate connectors C-12 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 relay 

connector C-203 (terminal 4) and front power window 
sub switch connector E-04 (terminal 7) 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 (RH) 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-04.

(1) Disconnect front power window sub switch connector E-04 

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.
