1. Loose or Missing Cover

The cover won’t stay in place, or it's completely missing.
Often caused by broken clips, tabs, or latches.
This can expose fuses to dust, water, or accidental contact, increasing the risk of electrical shorts.

2. Cracked or Broken Plastic

Visible cracks, warping, or missing pieces.
May happen due to:
Sun exposure (UV damage)
Age-related brittleness
Impact or careless removal

3. Rattling Noises in the Cab

If the cover is loose or doesn’t fit properly, it can vibrate or rattle when driving.
This is especially noticeable on rough roads or at higher speeds.

4. Poor Fit or Doesn’t Snap In

The cover no longer snaps in cleanly or sits flush with the panel.
May require constant adjustment or taping to stay in place.

5. Exposure to Dust or Moisture

If the cover isn’t sealing properly:
Dust or debris may settle on the fuses.
In worst cases, moisture can enter, leading to corrosion or shorts in the fuse panel.

6. Missing Fuse Diagram or Label

Some covers have a fuse layout diagram on the inside.
If this is missing or faded, it’s harder to identify and replace the correct fuse.
