Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to ensure safety during electrical work.

2. Check and Replace Fuse

Locate the fuse box (typically under the dashboard or in the engine compartment).
Identify the power window fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or needle-nose pliers.
Inspect the fuse; if it is blown, replace it with a new fuse of the same amperage (usually 30A for power windows).

3. Inspect and Replace Window Switch

Remove the panel surrounding the window switch using a trim removal tool.
Disconnect the wiring harness from the switch.
Test the switch with a multimeter; if it is defective, replace with a new switch.
Reconnect the wiring harness and reassemble the panel.

4. Test Window Motor

Remove the door panel to access the window motor (use a socket set to remove screws and clips).
Disconnect the window motor wiring harness.
Apply direct power from a 12V battery to the motor terminals to check its operation.
If the motor does not function, replace the window motor with a new one.

5. Reassemble Components

Reattach the door panel and ensure all clips and screws are secured.
Reconnect the battery.
