Turn signal problem

Car is 65 Dodge Coronet if it makes any difference. My right signal stopped working yesterday. Dash indicator comes on but doesn't blink. Sounds like burned out bulb, right? No such luck. Tail light comes but dosn't blink, front light comes on, on both sides but doesn't blink. Both front lights are dim while they are on. Any ideas? I thought maybe bad ground, but I don't see where they ground. Any help greatly appreciated.

Try cleaning out the bulb socket first- maybe the bulb isn't grounding all that well inside the socket.

check front/rear right side bulbs/sockets/grounds.
