1. Check the turn signal switch: Make sure the turn signal switch is in the correct position. If the switch is not in the correct position, the turn signals will not work.
2. Check the turn signal fuse: If the turn signal switch is in the correct position, check the turn signal fuse. If the fuse is blown, replace it with a new fuse of the same amperage.
3. Check the turn signal bulbs: If the fuse is not blown, check the turn signal bulbs. If a bulb is burned out, replace it with a new bulb of the same type.
4. Check the turn signal relay: If the bulbs are not burned out, check the turn signal relay. If the relay is faulty, replace it with a new relay.
5. Check the wiring: If all of the above steps have been completed and the turn signals still do not work, check the wiring. There may be a loose or damaged wire that is preventing the turn signals from working.
If you are still having difficulty getting your turn signals to work, it is best to have a qualified mechanic take a look at your F150 van.
