STEP 5. Check the front power window motor (RH).
(1) Remove the front power regulator assembly (RH). Refer to 

GROUP 42, Door-Door Glass and Regulator 

P.42-37

.

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

motor runs freely.

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

YES : Go to Step 6.
NO :  Replace the front power regulator assembly (RH). 

Verify that the front power window sub-switch (RH) 
should now work normally.

STEP 6. Check at front power window sub-switch 
connector H-16 in order to check the power window relay 
circuit of the power supply to the front power window sub-
switch (RH).
(1) Disconnect front power window sub-switch (RH) connector 

H-16, and measure at the harness side.

(2) Measure the voltage between terminal 5 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 9.
NO :  Go to Step 7.

STEP 7. Check power window relay connector D-219 and 
front power window sub-switch connector H-16 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.
Q: Are power window relay connector D-219 and front 

power window sub-switch (RH) connector H-16 in good 
condition?
YES : Go to Step 8.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

. Verify that the front power window sub-

switch (RH) should now work normally.

NOTE: Also check junction block connector D-208 and inter-
mediate connector D-15. If junction block connector D-208 or 
intermediate connectors D-15 is damaged, repair or replace the 
damaged component(s) as described in GROUP 00E, Harness 
Connector Inspection 

P.00E-2

.

Q: Is the harness wiring between power window relay 

connector D-219 (terminal 4) and front power window 
sub-switch (RH) connector H-16 (terminal 5) 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. Verify that 
the front power window sub-switch (RH) should now 
work normally.
