Solution

1. Preparation

Gather tools: flathead screwdriver, multimeter, socket set, and replacement fuses or components if necessary.
Disconnect the negative terminal of the battery to prevent electrical shocks.

2. Check Battery and Connections

Ensure the battery voltage is above 12.4 volts using a multimeter.
Inspect battery terminals for corrosion and tightness. Clean and secure as necessary.

3. Inspect Fuse Box

Locate the fuse panel (usually under the dashboard or in the engine compartment).
Identify the power window fuse using the diagram on the fuse panel cover.
Remove the fuse and inspect it for continuity; replace if blown with a new fuse of the same amperage (typically 30A).

4. Test the Window Switch

Remove the door panel using a flathead screwdriver and socket set.
Disconnect the wiring harness from the window switch assembly.
Use a multimeter to test for continuity in the switch; replace if defective.

5. Inspect Window Motor and Wiring

Locate the window motor in the door assembly after removing the door panel.
Check wiring connections to the motor for security and damage.
Use a multimeter to test the motor by applying power directly to see if it operates; replace if faulty.

6. Reassemble and Test

Reconnect all electrical connections and reattach the door panel.
Reconnect the negative battery terminal.
Test the power windows to confirm functionality.
