Check the power mode
Some sockets operate only in a specified ignition or accessory mode. Follow your vehicle manual. Never run an engine in an enclosed space.
Garage notes / Electrical basics
Car lighter socket not working? Start here.
A failed charger does not always mean a failed socket. Start with simple checks, refer to your vehicle manual, and stop if there are signs of damage or overheating.

Rule out the simple causes
Check the accessory
Unplug the adapter and cable. If they appear undamaged, compare with a known-good, compatible low-power accessory or another suitable working outlet.
Look without probing
Inspect the socket visually for damage or foreign objects. Do not insert metal tools, foil, fingers, or other objects into the socket.
If a fuse may have failed
Identify the exact circuit
Use the diagram for your model and year. Fuse labels and locations vary; do not choose a fuse solely because its label sounds similar.
Follow the removal procedure
Unplug accessories and follow the manual for shutdown and safe access. If the procedure or circuit is unfamiliar, use a qualified technician.
Match the specified fuse
Replace a confirmed faulty, user-serviceable fuse only with the exact type and amperage specified. Never bridge a fuse or install a higher rating.
Know when to stop testing
Heat or a burning smell
Stop using the outlet if you notice melting, discolouration, excessive heat, or a burning smell. Arrange professional diagnosis.
Repeated fuse failure
A replacement that fails again points to a problem that requires diagnosis. Repeatedly installing fuses does not correct the underlying fault.
Loose or intermittent power
A damaged socket, poor contact, or wiring problem may need electrical testing. Record which accessories and other sockets work before seeking help.
Useful answers
Questions before the next step.
Review the details that matter for your particular situation.
Can I use any spare fuse?
No. Use the exact fuse type and rating specified for that circuit. The fuse protects wiring and must not be bypassed.
What if the fuse looks fine?
A visual inspection cannot establish that the entire circuit works. Supply, wiring, contact, or accessory faults may require professional testing.
Can I plug in any 12V appliance?
Check the outlet power limit and the appliance requirements. A matching plug does not establish electrical compatibility.
