Solution

1. Preparation

Gather tools: trim removal tool, multimeter, socket set.
Ensure the vehicle is parked in a safe area and powered off.
Disconnect the vehicle’s battery to prevent electrical shock.

2. Inspect and Remove Door Panel

Use a trim removal tool to gently pry off the door panel clips.
Remove screws securing the door panel (typically located near the handle and bottom edge).
Carefully lift the door panel upwards to detach it from the clips.

3. Check Window Motor and Wiring

Locate the window motor; visually inspect for any signs of corrosion or damage.
Use a multimeter to test for power at the window motor connector.
- If no power is present, trace the wiring back to the fuse box.
- If power is present, the motor may need replacement.

4. Inspect and Replace Fuse

Locate the fuse box (refer to owner’s manual for exact location).
Identify the power window fuse using the diagram on the fuse box cover.
Remove the fuse and inspect it; replace if blown with one of the same amperage.

5. Reassemble Door Panel

Once repairs are complete, reattach the door panel by aligning it with the clips.
Secure screws back in place and ensure the panel is firmly attached.
Reconnect the vehicle’s battery.
