Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the power window fuse (refer to the owner’s manual for the exact location).
Remove the fuse using a fuse puller or needle-nose pliers.
Inspect the fuse for any signs of damage; replace it if blown with an identical fuse (usually 15 or 20 amps).

3. Inspect and Replace Window Switch

Remove the trim panel around the window switch (use a trim removal tool).
Disconnect the wiring harness from the window switch.
Test the switch for continuity with a multimeter; replace it if defective.
Reconnect the new switch and reassemble the trim panel.

4. Test and Replace Window Motor (if necessary)

Remove the door panel to access the window motor.
Disconnect the window motor wiring harness.
Test the motor by connecting it directly to the battery using jumper wires.
If the motor does not operate, replace it with a new motor.

5. Reassemble Door Panel

Ensure all connections are secure and components are properly installed.
Reattach the door panel, ensuring that all clips are engaged and screws are tightened.
