DOOR GLASS OTHER THAN DRIVER'S DOOR CANNOT BE OPERATED CANNOT BE OPERATED USING POWER WINDOW MAIN SWITCH OR EACH SUBSWITCH (POWER WINDOW SYSTEM) - DIAGNOSTIC PROCEDURE

Step	Inspection		Action
1	POWER WINDOW MOTOR CONNECTOR INSPECTION Switch the ignition off. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Disconnect the power window motor connector. Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. Is the connector normal?	Yes	Go to the next step.
1		No	Repair or replace the connector, then go to Step 7.
2	POWER WINDOW SUBSWITCH CONNECTOR INSPECTION Disconnect the power window subswitch connector. Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection. Is the connector normal?	Yes	Go to the next step.
2		No	Repair or replace the connector, then go to Step 5.
3	POWER WINDOW MOTOR TERMINALS E AND F INSPECTION Reconnect the disconnected connectors. Connect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Measure the voltage at power window motor terminals E and F while operating the power window subswitch. Terminal E during close operation Terminal F during open operation Is the voltage B+?	Yes	Replace the power window motor, then go to Step 5. (See FRONT POWER WINDOW MOTOR REMOVAL/INSTALLATION .) (See REAR POWER WINDOW MOTOR REMOVAL/INSTALLATION .)
3		No	Go to the next step.
4	POWER WINDOW SUBSWITCH INSPECTION Inspect the power window subswitch. (See POWER WINDOW SUBSWITCH INSPECTION .) Is the power window subswitch normal?	Yes	Refer to the wiring diagram and verify if there is a common connector between the following terminals. Power window subswitch terminal A and power window motor terminal F Power window subswitch terminal D and power window motor terminal E If there is a common connector: Inspect the common connector and terminals for corrosion, damage, or disconnection and the common wiring harnesses for an open or short circuit to determine the malfunctioning location. Repair or replace the malfunctioning location. If there is no common connector: Repair or replace the wiring harness which has an open or short circuit. Go to the next step.
4		No	Replace the power window subswitch, then go to the next step. (See POWER WINDOW SUBSWITCH REMOVAL/INSTALLATION .)
5	VERIFY IF MALFUNCTION CAUSE IS CORRECTED Does the power window system operate normally?	Yes	Troubleshooting completed. (Explain the problem to the customer.)
5		No	Verify the malfunction symptom in the symptom troubleshooting chart and perform the other applicable malfunction diagnosis.
