Solution

1. Preparation

Gather tools: socket set, multimeter, OBD-II scanner, screwdrivers.
Park the vehicle on a flat surface and turn off the ignition.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace Fuse

Locate the fuse box (usually found under the dashboard or in the engine compartment).
Remove the cover and find the power window fuse using the diagram on the fuse box cover.
Visually inspect the fuse for any physical damage; replace it with a new fuse of the same amperage if blown.

3. Test and Replace Switches

Remove the switch panel from the door using a flathead screwdriver or trim removal tool.
Use a multimeter to test the switch for continuity. If defective, replace with a new switch.
Reinstall the switch panel securely after replacement.

4. Inspect Wiring and Connectors

Carefully peel back the door panel to access the wiring harness connected to the power window motor.
Inspect for any damaged wires or loose connectors; repair or replace as necessary.
Ensure all connections are secure before reassembling.

5. Test Window Motor and Regulator

If the switches and wiring are intact, disconnect the window motor from the regulator.
Using a multimeter, check for voltage at the motor connector when the switch is activated.
If voltage is present but the motor does not operate, replace the window motor. If no voltage, further investigate wiring or control module.

6. Reassembly

Once repairs are complete, reassemble the door panel by aligning clips and screws.
Reconnect the negative battery terminal and test all power windows to ensure functionality.
