Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box (usually found under the dashboard or in the engine compartment).
Remove the fuse for the power windows using a fuse puller or needle-nose pliers.
Inspect the fuse for continuity using a multimeter.
Replace with a new fuse if blown (ensure to use the same amperage).
