well when i brought my car i turn on all the lights and they worked good when i get home the taillights short out and when light are on the tailllights dont turn on when i press the brake they do all bulbs are new and also my blinkers dont work at all not even the indicator light on the dash.... what could this be ? i was thinkin the blinkers could be the relay but idk any one got any clue about both of these lttle problems?

thanks
