Diagnostic Procedure

DRIVER-SIDE DOOR GLASS CANNOT BE OPERATED MANUALLY OR AUTOMATICALLY DIAGNOSTIC PROCEDURE

Step	Inspection		Action
1	POWER WINDOW MAIN SWITCH CONNECTOR INSPECTION Switch the ignition off. Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Disconnect the power window main switch 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 MOTOR CONNECTOR INSPECTION 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.
2		No	Repair or replace the connector, then go to Step 7.
3	VERIFY IF MALFUNCTION CAUSE IS POWER WINDOW MAIN SWITCH POWER SUPPLY CIRCUIT Reconnect all the disconnected connectors. Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Measure the voltage at the following terminals (vehicle wiring harness side). Power window main switch terminal 1B Is the voltage B+?	Yes	Go to the next step.
3		No	Inspect the P.WINDOW3 30A fuse. If any fuse is damaged: Replace the fuse. If the fuses are normal: Refer to the wiring diagram and verify if there is a common connector between the following terminals. P.WINDOW3 30A fuse and power window main switch terminal 1B 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 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 circuit. Go to Step 7.
4	VERIFY IF MALFUNCTION CAUSE IS OPEN CIRCUIT IN WIRING HARNESS BETWEEN POWER WINDOW MAIN SWITCH AND BODY GROUND Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Disconnect the power window main switch connector. Inspect for continuity between power window main switch terminal 1K (vehicle wiring harness side) and body ground. Is there continuity?	Yes	Go to the next step.
4		No	Refer to the wiring diagram and verify if there is a common connector between power window main switch terminal 1K and body ground. 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 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 is an open circuit. Go to Step 7.
5	POWER WINDOW MOTOR TERMINALS E AND F INSPECTION Reconnect all the disconnected connectors. Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Measure the voltage at power window motor terminals E and F while operating the power window main switch. Terminal E during close operation Terminal F during open operation Is the voltage B+?	Yes	Replace the power window motor, then go to Step 7. (See FRONT POWER WINDOW MOTOR REMOVAL/INSTALLATION .)
5		No	Go to the next step.
6	POWER WINDOW MAIN SWITCH 1 TERMINALS 1F AND 1D INSPECTION Measure the voltage at power window main switch terminals 1F and 1D. (See POWER WINDOW MAIN SWITCH INSPECTION .) Is the power window main switch voltage normal?	Yes	Refer to the wiring diagram and verify if there is a common connector between the following terminals. Power window main switch terminal 1F and power window motor terminal E Power window main switch terminal 1D and power window motor terminal F 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.
6		No	Replace the power window main switch, then go to the next step. (See POWER WINDOW MAIN SWITCH REMOVAL/INSTALLATION .)
7	VERIFY IF MALFUNCTION CAUSE IS CORRECTED Does the power window system operate normally?	Yes	Troubleshooting completed. (Explain the problem to the customer.)
7		No	Verify the malfunction symptom in the symptom troubleshooting chart and perform the other applicable malfunction diagnosis.
