Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shorts.
Ensure the workspace is clean and organized.

2. Inspect 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 pliers.
Inspect the fuse for continuity; replace it if blown with a fuse of the same amperage.

3. Test and Replace Window Switches

Reconnect the battery.
Use a multimeter to test the window switch for voltage when pressed.
If the switch is faulty, remove the door panel to access the switch.
Disconnect the switch connector and replace it with a new switch.

4. Inspect Window Motors and Regulators

With the door panel removed, locate the window motor and regulator assembly.
Check for any physical damage or obstructions in the regulator.
If the motor is unresponsive, disconnect it and test for functionality by applying direct power from the battery.
Replace the motor if it does not operate with direct power.

5. Reassemble and Test

Reinstall the door panel and secure all clips and screws.
Reconnect the battery and test the power windows to ensure proper operation.
