Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace the Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the power window fuse using the diagram on the fuse box cover.
Remove the fuse and inspect it; if blown, replace it with a fuse of the same amperage (typically 15A or 20A).

3. Test and Replace the Window Switch

Remove the door panel to access the window switch.
Disconnect the electrical connector from the switch and inspect for corrosion or damage.
Use a multimeter to test the switch for continuity. If faulty, replace with a new switch.

4. Inspect and Test the Window Motor

If the switch is functional, check the window motor.
Disconnect the motor from the window assembly.
Apply 12V directly to the motor terminals; if it does not operate, replace the window motor.

5. Check Wiring and Connections

Inspect the wiring harness for the window circuit for any breaks or frays.
Repair any damaged wires with solder or wire connectors and ensure all connections are secure.
