Solution

1. Preparation

Tools Required: Screwdriver set, multimeter, OBD-II scanner, wire stripper/crimper, replacement fuses (if needed).
Disconnect the vehicle battery to prevent electrical shock.
Allow the vehicle to sit for a few minutes to ensure all electrical systems are off.

2. Inspect and Replace the Power Window Switch

Remove the door panel using a screwdriver to access the power window switch.
Disconnect the electrical connector from the power window switch.
Use a multimeter to test the switch for continuity. If faulty, replace with a new switch.
Reconnect the new switch and reassemble the door panel.

3. Check and Replace the Window Motor

If the switch is functioning, remove the door panel again to access the window motor.
Disconnect the motor's electrical connector.
Use a multimeter to check for voltage at the connector when the switch is pressed. If voltage is present and the motor does not operate, replace the motor.
If no voltage is detected, trace wiring back to the switch and check for breaks or shorts.
Install the new motor if necessary, reconnect the electrical connector, and reassemble the door panel.

4. Inspect and Replace Fuses and Wiring

Locate the fuse box and identify the fuse for the power windows (refer to the owner's manual).
Remove the fuse and inspect it; replace if blown.
If wiring damage is found during the inspection, splice in new wire as necessary and secure all connections.
