STEP 9. Check the wiring harness between power window 
main switch connector H-05 (terminal 3) and ground.

NOTE: Also check intermediate connector D-25 for loose, cor-
roded or damaged terminals, or terminals pushed back in the 
connector. If intermediate connector D-25 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 H-05 (terminal 3) and ground 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

STEP 10. Check the battery power supply circuit to the 
power window main switch. Test at power window main 
switch connector H-05.
(1) Disconnect power window main switch connector H-05 and 

measure the voltage available at the harness side of the 
connector.

(2) Turn the ignition switch to "ON" position.

(3) Measure the voltage between terminal 5 and ground.

• The voltage should be approximately 12 volts (battery 

positive voltage).

Q: Is the measured voltage approximately 12 volts (battery 

positive voltage)?
YES : Go to Step 13.
NO :  Go to Step 11.

STEP 11. Check power window main switch connector H-
05 and power window relay connector D-219 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.
Q: Are power window main switch connector H-05 and 

power window relay connector D-219 in good 
condition?
YES : Go to Step 12.
NO :  Repair or replace the damaged component(s). Refer 

to GROUP 00E, Harness Connector Inspection 

P.00E-2

NOTE: Also check junction block connector D-208 and inter-
mediate connector D-25 for loose, corroded or damaged termi-
nals, or terminals pushed back in the connectors. If junction 
block connector D-208 or intermediate connector D-25 is dam-
aged, repair or replace the damaged component(s) as 
described in GROUP 00E, Harness Connector Inspection
