Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety during the repair.

2. Inspect and Replace Fuses

Locate the fuse box (typically under the dashboard or in the engine compartment).
Identify the fuse for the power windows (refer to the owner's manual for the correct fuse location).
Remove the fuse using a fuse puller or pliers.
Inspect the fuse; replace it if it is blown with a new fuse of the same amperage.

3. Check Window Switches

Remove the door panel using a trim tool and screwdriver.
Disconnect the window switch connector and use a multimeter to check for continuity.
If the switch is faulty, replace it with a new switch.

4. Test Wiring and Connections

Inspect wiring harnesses for signs of wear, fraying, or corrosion.
Clean any corroded connectors using electrical cleaner and reconnect securely.
If any wiring is damaged, repair or replace the affected sections.

5. Test Window Motors

Disconnect the window motor from the door.
Use jumper wires to connect the motor directly to a 12V power source (ensure proper polarity).
If the motor operates, it is functioning; if not, replace the window motor.
