Blinkers not working

You have dual element bulbs. Tail is seperate from brake and turn. Check the bulb the brake/turn element is burned.

Check turn signal flasher relay. If OK suspect faulty signal switch.

Did you check this fuse?

If both fuses are good, consider replacing the flasher unit. If that does not solve the issue, the problem may lie within your multi-function switch.

Intermittent issues are hard to fix since they aren't always inoperative. Most likely the flasher unit is bad though

The flasher sits above the gas pedal behind a small, black panel. The panel is held on with one star bolt and is situated between the gas panel arm and the bottom of the plastic molding that sits below the steering column. The flasher should be be green and clipped to a small, cube shaped harness and attached to the inside wall by two plastic clips. You will need to use a very small flat head to pry the two pieces apart. After removing the part you can verify that you have the correct replacement by comparing units, often times without opening the packaging on the replacement. Secondly you can verify that you did remove the flasher by putting your keys in the ignition, turning the on and then using your turn signals or hazards.
