Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Check and Replace Fuse

Locate the fuse box, typically in the driver's footwell or under the dashboard.
Remove the fuse related to the power windows using a fuse puller.
Inspect the fuse; if it is blown, replace it with a fuse of the same amperage (usually 30A for power windows).
Reconnect the negative battery terminal and test the windows.

3. Replace Window Switch (if necessary)

Remove the door panel using a socket set and trim removal tools.
Disconnect the wiring harness from the window switch.
Replace the old switch with a new one.
Reconnect the wiring harness and reassemble the door panel.

4. Inspect and Replace Window Motor (if necessary)

If the switch is functional, locate the window motor behind the door panel.
Disconnect the wiring harness from the motor.
Apply direct battery power to the motor using jumper wires to check for operation.
If the motor does not work, remove it by unfastening the mounting screws.
Install the new window motor and reconnect the wiring.
