Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the fuse for the power windows using a fuse puller.
Inspect the fuse for continuity; if blown, replace it with a new fuse of the same amperage (typically 30A).
Reconnect the battery and test the window operation.

3. Test Window Switches

Remove the door panel using a socket set to access the window switches.
Disconnect the wiring harness from the switch and use a multimeter to check for continuity when the switch is pressed.
If the switch is faulty, replace it with a new switch and reassemble the door panel.

4. Inspect Wiring and Connections

Check the wiring harness for any frayed wires or loose connections.
Repair any damaged wiring with electrical tape or replace the harness if necessary.
Ensure all connections are secure and reassemble the door panel if previously removed.

5. Test Window Motor

If the switches are functioning, but windows still don’t operate, remove the window motor from the door.
Using a 12V power source (such as a battery), apply power directly to the motor terminals.
If the motor does not operate, replace the window motor with a new unit.
