No regular fuse for headlamps , fusible link .Do you know what a fusible link is ? There is a headlamp switch , dimmer switch , no relay . Go http://www.bbbind.com/free_tsb.html free wiring diagrams ! Check it out yourself , an check for B+ voltage with a DVOM - digital volt ohm meter at the headlamp switch , if B+ voltage is present there check at dimmer switch . There are videos on youtube for basic automotive electrical testing . Do you know how to read a wiring diagram ? Videos on youtube for that as well .

check fuses and relays ----re check your fuses and relays as well as battery block and ground straps if all good will need a meter to back trace and search for possible wire short or melted wiring in harness

I would say either the fuse or the switch, maybe a bad wire.

sounds like you have rats in your dash,or someone has been doing some rewiring,there has to be wires shorted together wired together

This would be like looking for a needle in a hay stack, the right way would be to get a wiring diagram showing wiring from INT BAT and tracing the wires to make sure if its not short to ground.
And dont put fuse more then 50amp or else the wiring will melt and you may have fire.

The brake light fuse is located inside the the fusebox, i have enclosed two diagrams to show you what every fuse is for and the other is the fuse box and the locations are numbered, i hope this is helpful.

A wire from the cluster is shorted to ground, must check and inspect wiring diagram for the cluster.

That is your EDU unit it has to be fitted back to get a good ground connection.

check the back of the fuse box cover. You may find your answer there.
