Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the blown power window fuse and replace it with a new one of the same amperage.
Reconnect the battery and test the power windows to see if the issue persists.

3. Check and Replace Power Window Switch

If the fuse continues to blow, remove the power window switch from the door panel.
Inspect the switch for signs of damage or burnt contacts.
If damaged, replace the switch with a new one, ensuring all connections are secure.

4. Inspect Wiring Harness

Remove the door panel to access the wiring harness connected to the power windows.
Visually inspect the wiring for any frays, cuts, or signs of wear.
If damage is found, repair the wiring by splicing in new wire or replacing the harness as necessary.

5. Test Power Window Motors

Disconnect the power window motor connectors.
Using a multimeter, test the motors by applying direct power to see if they operate.
Replace any motors that do not function properly.

6. Reassemble Components

Reattach the door panel and ensure all clips and screws are secure.
Reconnect the battery and perform a final test on the power windows.
