94 Accord Headlight Prob.

I wrecked my 94 accord a bit back and just rebuilt it all. My driving lights ( taillights, instrument panel lights, and parking lights) dont work. The fuse for these have a constant 12v source. Is it supposed to be a 12v source constantly even when the switch is off? So i cant replace the fuse because it will blow instantly. Now my high beams wont go off either. Think it is just a bad switch or what? If i hook a constant straight from the positive of battery to the lights they all work. But if i turn the switch on when im doing this they go off. Help. Thx

it could be the switch on you could have a grounded wire somewere because of the acident
