Just pull all the fuses out and check them. Replace the bad one.
that's not really going to help.... remove the cigarette lighter by pulling the trim off the radio there is a fusable link on the cigarette lighter socket itself. you can replace the socket or try to replace the fuseable link its a peice of 14 gauge aluminum wire....
Also you need to be sure the fuse is working in your car before replacing the lighter.
To remove a cigarette lighter from a Toyota 4Runner, pull the lighter straight towards you. Pull gently until it becomes free.
If the cigarette lighter is not working and the ACC fuse, inside the car, left of steering wheel, is still good (radio is working), the "fuse" on the back side of the cigarette lighter socket, a brown wire, has blown. Socket needs to be replaced or fixed with a soldering iron and a new wire.
your 15 A fuse located behind the coin box is blown.
In the ash tray at the bottom of the centre console.
Is cigarette lighter not working also? If so then probably a fuse blown by shorting the cigarette lighter socket. Fuse is located under glove box passenger side front (RHD version). It's not easy to get to and will probably be the last one you try.
