Solution

1. Preparation

Tools Required: Socket set, multimeter, OBD-II scanner, wire connectors, electrical tape.
Disconnect the battery negative terminal to ensure safety while working on electrical components.

2. Inspect and Replace Fuses

Locate the fuse box (typically under the dashboard or in the engine compartment).
Remove the power window fuse using a fuse puller or pliers.
Inspect the fuse for any breaks or damage; replace it if necessary with a fuse of the same amperage.

3. Check Window Switch

Remove the door panel to access the window switch.
- Sub-steps:
  - Use a trim removal tool to gently pry off the door handle cover.
  - Unscrew any visible screws holding the door panel.
  - Carefully detach the panel from its clips and lift it away.
Test the switch with a multimeter for continuity when pressed.
If defective, replace the switch.

4. Inspect Wiring and Connectors

Examine the wiring harness leading to the window motor for any frays or disconnections.
Clean any corroded connectors with electrical cleaner and reconnect them securely.

5. Test and Replace Window Motor

If previous steps do not resolve the issue, the window motor may need replacement.
- Sub-steps:
  - Disconnect the wiring harness from the window motor.
  - Remove the motor from the door assembly by unscrewing any retaining screws.
