2. Check the turn signal switch. The turn signal switch is located on the steering column. If the switch is faulty, it will need to be replaced.
3. Check the wiring. The wiring for the turn signals and hazard flashers may be damaged, causing them not to work. Check the wiring for any loose, broken, or frayed wires. If there is damage, the wires will need to be repaired.
4. Check the taillight bulbs. If the turn signal bulbs are not working, the taillight bulbs may also be burned out. Replace any burned out bulbs.
