Repair the connector.

Step 10. Check the wiring harness from F-16 
power window motor (front: RH) connector 
terminal Nos.1 and 3 to F-15 power window sub 
switch (front: RH) connector terminal Nos.5 and 
7.

• Check the input and output lines for open or short 

circuit.

Q: Is the check result normal?

YES : 

Go to Step 11.

NO : 

Repair the wiring harness.

Step 11. Retest the system.
