OEM Toyota Turn Signals

Likely Reasons Your Turn Signal Isn't Working (And How to Fix)

Your turn signals are one of the most critical safety features on your Toyota Corolla. When they stop working, the problem could range from a simple bulb replacement to a deeper electrical issue. Knowing how to diagnose and fix common problems keeps you safe and compliant with the law.

Is a Broken Turn Signal a Traffic Violation?

In most states, a malfunctioning turn signal is considered a moving violation and can lead to a ticket or fine. Driving with defective turn signals also increases your risk of causing or being involved in a collision.

Common Turn Signal Problems and How to Fix Them

1. Burnt-Out Bulb

If your signal is flashing rapidly or not at all, a bulb in your turn or tail light assembly may have burned out and needs replacement.

2. Blown Fuse

A blown fuse in the signal circuit will disable the system entirely—replace it with one that matches the correct amperage.

3. Faulty Flasher Relay

If both signals stop working at once or behave erratically, the flasher unit may be the culprit and should be replaced.

4. Broken Turn Signal Switch

When the stalk feels loose or doesn’t activate lights, the internal switch could be faulty and may require full stalk replacement.
