Solution

1. Preparation

Gather tools including a screwdriver set, multimeter, and panel removal tool.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect the Fuse

Locate the fuse box (usually found under the dashboard or in the engine compartment).
Remove the fuse associated with the power windows using a fuse puller or needle-nose pliers.
Visually inspect the fuse for any breaks in the metal strip; replace with a new fuse of the same amperage if necessary.

3. Access the Window Motor

Use a panel removal tool to carefully detach the door panel.
Remove any screws or clips holding the panel in place.
Lift the door panel away and disconnect any electrical connectors attached to it.

4. Check the Window Switch

Use a multimeter to measure resistance across the switch terminals.
If there is no continuity when the switch is pressed, replace the switch.
Reconnect the switch and the window motor temporarily to test for functionality.

5. Test the Window Motor

With the window switch activated, measure the voltage at the motor connector.
If voltage is present and the motor doesn’t operate, replace the window motor.
If no voltage is detected, further investigate the wiring or switch issues.

6. Reassemble

After completing repairs, reconnect any electrical connectors and reattach the door panel.
Ensure all clips and screws are secured properly.
Reconnect the negative battery terminal.
