Just bought a 1990 Beretta yesterday, the third brake light comes on but the 2 tail lights won't light up when the brake is appiled also the hazard flashers won't work in the rear either, but, the turn signals work the running lights also work, just no brake lights. Please help

 

nevermind, i figured it out, its the turn signal switch, the signals and the brake lights both work when you pull the lever toward you, how hard is this to change?
