no brake lights or left turn signal. how do i fix it
again...the system ground...follow the black battery cable...will be attached to the chassis frame at a delicate point that pulls 300 or more cold cranking amps through that one spot and eventually gets corroded from high amperage exchange of dis-similar metals...wirebrush the lug....wirebrush the chassis and bolt them together for a refreshed ground for the lightbulbs, ECU etc~
Also it could be the housing where you plug in the light bulbs may need replacing depending on the model
