Solution

1. Preparation

Tools Required: Screwdriver set, multimeter, OBD-II scanner, wire connectors.
Disconnect the negative terminal of the battery to ensure safety.

2. Check and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the power window fuse using a fuse puller.
Inspect the fuse for continuity; replace with the same amperage fuse if blown.

3. Inspect Window Switch

Remove the door panel using a screwdriver to access the window switch.
Disconnect the wiring harness from the switch.
Test the switch with a multimeter to ensure it is sending power when pressed. Replace if defective.

4. Check Window Motor

If the switch is functional, disconnect the window motor from the wiring harness.
Use jumper wires to connect the motor directly to the car battery.
If the motor operates, the issue lies with the wiring or switch. If it does not operate, replace the window motor.

5. Reassemble Components

Reconnect all wiring harnesses and ensure everything is secure.
Reattach the door panel, ensuring all clips are properly engaged.
Reconnect the negative battery terminal.
