Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shock.
Ensure you have adequate workspace and lighting.

2. Inspect and Replace Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Remove the power window fuse using a fuse puller or needle-nose pliers.
Examine the fuse for continuity; replace if blown with the same amperage rating.

3. Test and Replace Window Switches

Remove the door panel to access the window switch assembly.
Disconnect the switch connector and use a multimeter to check for continuity.
If faulty, replace the switch with a new one by reversing the removal process.

4. Inspect Wiring and Connectors

Visually inspect the wiring harness for fraying or breaks, especially around the door hinges.
Repair any damaged wires using appropriate electrical tape or heat-shrink tubing.
Ensure all connectors are clean and securely connected.

5. Test and Replace Window Motors

If the switches are operational, remove the window motor from the door.
Apply a direct battery voltage to the motor terminals to see if it operates.
If the motor does not function, replace it with a new motor.
