Solution

1. Preparation

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

2. Inspect and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the power window fuse and inspect for any signs of a blown fuse.
Replace with a new fuse of the same amperage if necessary.

3. Access and Test Window Switches

Remove the door panel using a socket set and trim removal tools.
Disconnect the wiring harness from the power window switch.
Test the switch for continuity; if faulty, replace it with a new switch.

4. Test and Replace Window Motor

Disconnect the window motor's connector.
Using jumper wires, apply direct battery voltage to the motor terminals to test operation.
If the motor does not operate, replace with a new window motor.

5. Inspect Wiring Harness

Examine the wiring harness leading to the window motor and switches.
Repair any damaged wires using solder and heat-shrink tubing or replace the entire harness if necessary.

6. Reassemble Components

Reattach the door panel securely using screws and clips.
Reconnect the battery and test the window operation.
