Solution

1. Preparation

Gather tools: socket set, multimeter, flathead screwdriver, and Phillips screwdriver.
Disconnect the battery to avoid any electrical shorts.

2. Inspect and Replace Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the cover and identify the fuse related to the power windows.
Use a fuse puller or pliers to remove the fuse and inspect it.
If blown, replace it with a fuse of the same amperage.

3. Test and Replace the Power Window Switch

Remove the door panel using a flathead screwdriver and Phillips screwdriver.
Disconnect the power window switch connector.
Set the multimeter to the continuity setting and test the switch.
If the switch is faulty, replace it with a new one.

4. Inspect and Test the Window Motor

With the door panel removed, locate the window motor.
Disconnect the motor's wiring harness.
Use the multimeter to check for voltage at the motor connector while pressing the window switch.
If there is power but the motor does not operate, replace the window motor.

5. Reassemble Components

Ensure all connections are secure and no wires are pinched.
Reattach the door panel and secure it with screws.
Reconnect the battery.
