Solution

1. Preparation

Gather tools: socket set, multimeter, flathead screwdriver, Phillips screwdriver.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace Fuse

Locate the fuse box (usually found under the dashboard or in the engine compartment).
Remove the power window fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace it with a new fuse of the same amperage if blown.

3. Inspect and Replace Power Window Switch

Remove the door panel using a flathead screwdriver and Phillips screwdriver to access the switch.
Disconnect the wiring harness from the power window switch.
Test the switch with a multimeter; if defective, replace it with a new switch.
Reconnect the wiring harness and secure the door panel back in place.

4. Test Window Motor

If the switch is functional, locate the window motor by removing the door panel.
Disconnect the motor from the window regulator.
Use a multimeter to check if the motor receives power when the switch is pressed.
If there is power but no operation, replace the window motor.

5. Inspect Wiring and Regulator Assembly

Check the wiring harness connected to the window motor for any damage or loose connections.
Inspect the window regulator for any mechanical issues, such as a jammed or broken cable.
If the regulator is damaged, replace it with a new regulator assembly.
