me thinks exactly what he says ^^^^

sounds like ur getting a short sumwhere on fuse1, if its not blowing i wud guess that either the fuse is blown u just cant see the break or one of the wires on the back of fuse1 has come adrift

ok im at that stage where everything goes wrong at once, and i am hating my car, today for some reason i noticed the mfd display was not working, then i also noticed the hazard light, interior light, horn and my head unit all did not work! looked at the fuse thing and they are all on the same fuse..but the fuse has not blown. sometimes the mfd comes on and it has totally reset itself but if i try turn the head unit on, or press the horn they dont work and the mfd goes off again!
Whats going on, i really need your help coz is p155ing me off and im considering buying a saxo! any help would be brilliant
