What Causes the Turn Signal to Flash Too Fast When It's Not Broken?

[BryceLynn]

The reasons why the turn signal flashes too fast when it's not broken are as follows: one possibility is a damaged flasher relay, and another is poor bulb contact. Here are the solutions to fix a turn signal flashing too fast: 1. Replace the flasher relay: First, check if the flasher relay is functioning properly. Use a multimeter to test the output line of the flasher relay to see if there is a 12v output. If there is an intermittent output change, it indicates normal operation. If there is no output or a constant 12v output, it means the flasher relay is damaged and needs to be replaced. 2. Reinstall the bulb: Inspect the bulb and socket yourself to check for poor contact. Poor contact can naturally cause the signal to flash too fast, so you need to reinstall it securely.
