There are two fuse boxes, one under hood and another under dash board. For lighter, audio system, you need to replace the one under dash board.
Here is an answer given by someone call "Mark". I just copy paste his answer here. This answer works for me.
The owner's manual is lacking in regard to the location of the cab's fuse panel. Get a flashlight. With the driver's seat in the far back position, lay on your back with your head on the brake pedal. Look up BEHIND the dash, approximately behind where the white connector is on the front of the dash that you thought the owner's manual was referring to. You will see a black cover approximately 1" x 6" with fuse designations on it. Remove. Looking left to right, your fuse is the blue 15A in the center of the row closest to the dash. It is designated on the cover as "CIG." Use a pair of needlenose with the jaw wrapped in tape to remove. Replace with spare in engine compartment fuse box. Put the under-dash cover in glove box to make next time easier.
The clock is protected by two separate 15 Amp fuses on also protects the dome light (marked Dome in fuse box) the second protects the cigarette lighter (marked CIG in fuse box).
Make sure nothing has jammed in your cigarette lighter that may have caused the fuse to initially blow..
Interior fuse boxes are usually to the lower left of your dash panel, or by the driverside kick panel (by your left foot). In my experience Toyota's have very good and detailed owner's manuals so I suggest looking there if your Corolla came with one. hope this helps!
