HELP im ready to give up. thanks

 

Have you checked the bulbs? Bulbs can short out and flow fuses, since the rear turn and brake lamps share a filament, I would pull the front bulbs and try again. And welcome to the forum.

 

i've checked everything and unpluged everything and still blowes the fuse

 

Are you sure fuse 2.7 does not go to the headlight switch?

Or did you mean fuse 2.27? (this fuse controls the circuits you describe)

 

the fuse is 2.27

 

The 2.27 fuse is blowing, NOT the 2.7 ?
