I need to know what size fuses go where?

have you had a look at the back of the head unit? maybe a loose wire? or your radio is just stuffed and may need replacing

u should have 2 fuses boxes 1 in the cab and 1 in the engine bay.

Can you turn on the lights with the Interior light switch?. If a light works, obviously the fuse is good. You will need a wiring diagram and a test light to figure out where to start.

Fuses blow to protect the wiring. You probably have a shorted wire somewhere, or you are using fuses that are the wrong size.

Engine size and trans would be hepful information.......fuses in the cab? this is a Camry right? Check the 3 main fuses in the fuse box under the hood, then check ALL fuses.

Check fuses first to see that you have noon of them blown.

I have a 01 f150 reg cab I had to replace mine I believe it is the number 8 fuse if it is a factory fuse it should be a 5 amp fuse

The car dash probably lights the radio dial so that it will dim down with the dash light dimmer. The radio light may still be switched on and off by the radio switch but its a separate circuit. Check the fuse for the circuit that powers the radio itself. It should have its own fuse. Its likely that the radio has failed and will have to be removed and checked on a bench but check the fuse and check the power and antenna connectors in the back of the radio as these sometimes come loose from vibration. Always replace a fuse with one of the exact same amperage, voltage rating, and time delay if any as the original. If a fuse is blown the cause may be internal to the radio or it may be a problem with the car wiring to the radio. If blown check the wiring leading to the radio for worn insulation near sharp edges in the dash.

you should refer to your owners manual for the fuse size. if you are only missing 1 fuse and every thing else works ,Then my guess would be that is your reason for a non working radio. As well the fuse may have been removed due to a ground in the wiring.

I have a ford f 250 4x4 2003 and my horn doesnt work and the overhead compass/information instrument will not turn on. the airbag light blinks a few times them stays on. whats the deal?
