Turn signals that do not work is almost always, a blown fuse, bad bulb, corroded socket, or a defective flasher relay. If the lights come on but do not flash, it is the flasher relay. If the light does not come on, the bulb is bad or the socket is corroded. If one light flashes very fast then your front/rear light may be burnt out. If no lights come on, then your fuse is blown.
It could be as simple as a fuse. Or as hard as a multi-funtion switch. Which means the switch for your turn signals.
