Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the vehicle to cool if the engine has been running.

2. Check and Replace Fuse

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

3. Inspect and Replace Power Window Switch

Tools Required: Screwdriver set, trim removal tool
Carefully remove the door panel using a trim removal tool.
Disconnect the switch connector and inspect for damage.
Replace the switch if necessary by unscrewing it from its housing.

4. Test and Replace Window Motor (if needed)

Tools Required: Multimeter, basic hand tools
Remove the door panel as per the previous step.
Disconnect the window motor connector.
Use a multimeter to check for voltage at the motor connector while pressing the switch.
If no voltage is present, check wiring and relay; if voltage is present but the motor does not operate, replace the window motor.

5. Reassemble Door Panel

Reconnect all wiring and components back in their original positions.
Reattach the door panel carefully, ensuring all clips and screws are secure.
