Solution

1. Preparation

Gather tools: socket set, screwdriver set, multimeter, wire connectors, and electrical tape.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box (consult the owner's manual for exact location).
Remove the power window fuse using pliers.
Inspect the fuse for continuity using a multimeter; replace it if blown.
Reinstall the fuse and reconnect the battery.

3. Test and Replace Power Window Switch

Remove the door panel using a screwdriver to access the switch.
Disconnect the switch harness and use a multimeter to check for voltage.
If no voltage is present, replace the switch with a new one by connecting the new switch to the harness and securing it back in place.

4. Check and Replace Window Motor

If the switch is functional, access the window motor by removing the door panel.
Inspect the motor connections for corrosion or damage.
Use a multimeter to test the motor; if it does not respond when power is applied directly, replace the motor.
Install the new motor by aligning it with the window mechanism and securing it with screws.

5. Reassemble Door Panel

Reconnect all wiring and ensure that no wires are pinched.
Reattach the door panel using screws and clips.
Test the power window function before completely securing the door panel.
