Symptoms
- No power at all to the outlet
- Other accessories on the same fuse also stopped working
- Outlet worked fine until a specific device was plugged in
- No light or click when device is inserted
Likely causes
- CommonBlown fuse from an overloaded or shorted accessoryPhone chargers, air compressors, or other high-draw devices can blow the fuse.
- PossibleDebris inside the socket preventing contactCoins or lint can block the connection without blowing a fuse.
- PossibleFaulty accessory plugged in causing repeated blowsA specific device might have an internal short causing the fuse to blow repeatedly.
- Less commonWiring damage to the outletPhysical damage or corrosion in the socket itself can cause failure.
What to do
- Unplug whatever was last connected before the outlet stopped working.
- Check the fuse box (refer to owner's manual for location and diagram) for a blown outlet fuse.
- Replace with a new fuse of the same amperage rating, never higher.
- Test the outlet with a different, known-working device like a phone charger.
- If the new fuse blows immediately, stop and suspect a short rather than replacing fuses repeatedly.
- Inspect the socket for debris with a flashlight and remove carefully with a plastic tool.
- Avoid plugging in high-draw accessories (like tire inflators) for extended periods if the fuse keeps blowing.
- Have a shop check the wiring if a fresh fuse blows again with nothing plugged in.
