ok i have and 85 camaro z 28. I have no speedometor wipers or blinkers. the only time the blinkers work is when i turn on the hazerds and even then only the left front and the right rear work. I replaced all the bulbs and checked all fuses. and to make things even more crazy is the arrows in the dash both turn on when i turn on when i turn the head lights on and only the left one blinks when hazerds are on or other wise they dont work. when i bought the car the guy said the interior was out of a 91 camaro

 

UNPLUGYOUR HEADLIGHT SWITCH AND SEE WHAT THAT DOES....
