Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Check and Replace Fuses

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the fuse for the power windows using the diagram.
Remove the fuse and inspect it; replace it if it appears blown.
Reconnect the negative battery terminal and test the windows.

3. Inspect and Replace the Window Switch

Remove the door panel using a screwdriver and trim removal tool.
Disconnect the power window switch harness.
Use a multimeter to test for continuity in the switch.
If faulty, replace the window switch with a new one.
Reassemble the door panel and test the window operation.

4. Test and Replace the Window Motor

If the switch is functional, locate the window motor in the door.
Disconnect the motor wiring harness.
Using jumper wires, apply direct battery power to the motor to test its function.
If the motor does not operate, remove it from the door and replace it.
Reconnect everything and test the windows again.
