Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety during repairs.

2. Inspect and Replace the Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the power window fuse using the fuse box diagram.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace if blown with a new fuse of the same amperage.

3. Test and Replace the Power Window Switch

Remove the door panel to access the power window switch.
Disconnect the wiring harness from the switch and inspect for damage.
Test the switch with a multimeter for continuity; replace if faulty.
Reinstall the new switch or reattach the existing one if functional.

4. Check and Replace Window Motors

If the switch is functional, access the window motor by removing the door panel.
Disconnect the motor's electrical connector.
Test for power at the motor connector when the switch is activated.
If no power is present, trace wiring for issues; if power is present, replace the window motor.

5. Reassemble the Door Panel

Once repairs are completed, reassemble the door panel.
Ensure all clips and screws are securely fastened.
Reconnect the negative terminal of the battery.
