i have a 1986 ramcharger and the brake lights and turn signals arent workin what would cause this? when i turn on on of the signals they both blink and the brake lights dont work unless the headlights are off!
Make certain all the bulbs are working properly.
Unless there is a short somewhere, (perhaps in a bulb socket) the flasher itself may be faulty.
There also could be a fault with the multi-function switch. (turn signal lever)
Check the grounds at the rear light sockets.
