I have a 1993 honda civic and last night i went to turn my lights on and a fuse blew. My tail lights, license lights, bright lights, and dashboard lights went out, and my speedometer doesn't work. When i try to put a new fuse in it blows. Does anyone know what to do????

 

You have a short somewhere. Was anything installed recently, any modifications anywhere on the car? Possibly a screw shot through a wire somewhere.

 

I had work done on my radiator the day it happened, I also installed a system(head unit, subs and amp)

 

I'll bet it's a shorted wire somewhere. Most likely something with the stereo install. There is a dimmer wire that is in the stereo harness, probably shorted out. If you had it done somehwere I would take it back, if you did it trace all you r steps, look everywhere you ran wires or insalled something, and where you screwed the amp down, etc.

 

check your head unit wiring harness. there is one wire that u didnt need, i think it is the orange one. tape it up it is probably the one causing the short. I had the exact same thing
