My cigarette lighter fuse blew, we replaced it and the fuse blew again within a day what do i need to do

Possibly but more likely you've disturbed the wiring and it is now causing a short circuit

Research what else is on the circuit. In the old days when cars had more than one cigarret lighter I discovered that a penny fits in the socket perfectly and would cause a short.

If you replace the fuse again and it blows then you have a short somewhere, usually in an accessory you're plugging into it, or in the actual lighter. If it just blew randomly and replacing the fuse fixes the problem then I wouldn't worry about it. Sometimes they blow prematurely.

Replace the lighter it is shorted out, the lighter is Held in by a big stamped nut on the bank of the threaded barrel.

change the socket

you could be lucky and the fuse blew, and it could be a burned wire, check the fuse panel and replace the fuse if blown, if it blows again you have to fix the wires, and possible the cigarette lighter if it got damaged

put a circit breaker in place of fuse. use a regular compass and run the compas around wiring and if compas moves thats where the short is within 6 inches. shorts create a magnetic feild

On the left side fuse housing it should be marked on cover (cigarette lighter) replace with same style fuse only 5amps greater in size.

Two years later and you solved my dead cigarette lighter. manual says fuse 35--but it did not say to check 38 on the left fuse box. Thanks--blown fuse and everything works. Thanks
