Gather tools and materials: flathead screwdriver, T20 Torx screwdriver, multimeter, replacement fuses (if necessary).
Ensure the vehicle is parked on a level surface and turned off.
Disconnect the vehicle battery for safety.

2. Inspect and Replace Fuses

Locate the fuse box: Refer to the owner's manual for the exact location of the power window fuses.
Remove the fuse box cover: Use a flathead screwdriver to gently pry off the cover.
Check the fuses: Identify the power window fuses (usually labeled) and visually inspect them for any signs of damage.
Replace blown fuses: If a fuse is blown, replace it with a new fuse of the same amperage.
