YES : 

Intermittent malfunction (Refer to GROUP 

00 

− How to Use 

Troubleshooting/Inspection Service Points - 
How to Cope with Intermittent Malfunction .)

NO : 

Replace the front power window motor (LH).

INSPECTION PROCEDURE C-3: Relevant power window(s) does not work by means of the front and 
rear passenger's power window sub switches.

COMMENTS ON TROUBLE SYMPTOM

If the front passenger's or rear power window(s) do 
not work by means of the respective power window 
sub switch, a malfunction of the power window sub 
switch or the power window motor is suspected. 
Also, the power window lock switch ON signal may 
be sent from the power window main switch, 
because the power window lock switch of the power 
window main switch is ON, or the power window 
main switch has a malfunction.

PROBABLE CAUSES
