Solution

1. Preparation

Gather tools: screwdriver set, multimeter, wire strippers, and electrical tape.
Disconnect the battery to prevent electrical shock.

2. Inspect and Replace Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Remove the cover and locate the power window fuse.
Use a multimeter to check for continuity in the fuse; replace if blown.
Reinstall the fuse and cover.

3. Check Window Switches

Remove the door panel using a screwdriver to access the window switch.
Disconnect the switch connector and inspect for corrosion or damage.
If defective, replace the switch with a new unit.

4. Test Window Motor

Disconnect the window motor from the regulator.
Use jumper wires to connect the motor directly to the battery (positive to positive, negative to negative).
If the motor operates, the issue lies within the wiring or switch; if it doesn't, replace the motor.

5. Inspect Wiring Harness

Check the wiring harness for any frayed wires or loose connections.
Repair or replace any damaged wires and ensure secure connections.
Reassemble the door panel.
