Q: Is the wiring harness between power window main 

switch connector E-12 (terminals 6 and 14) and rear 
power window sub switch (RH) connector E-06 
(terminals 5 and 8) in good condition?
YES : Replace the power window main switch. When the 

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

STEP 31. Check the wiring harness between rear power 
window sub switch (RH) connector E-06 (terminals 4 and 
7) and rear power window regulator motor (RH) connector 
E-07 (terminals 1 and 2).

Q: Is the wiring harness between rear power window sub 

switch (RH) connector E-06 (terminals 4 and 7) and rear 
power window regulator motor (RH) connector E-07 
(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 
rear power window sub switch (RH) is operated, the
