Why My Turn Signals Don’t Work ~ Diagnosis – Humble Mechanic

how to check fuses

how to check fusesAfter driving around with no turn signals for an embarrassing amount of time, I finally had a chance to diagnose why my turn signals were not working. They failed in a different way. Often when a turn signal doesn’t work right, the turn signal bulb flashes fast. This was not the case in my car.

As you will see, we talk the path for a complete diagnosis of the turn signals. There are many ways that a mechanic may diagnose this issue. I really want to start exposing you guys to my diagnostic approach to issues. Then it’s up to you to form you own strategies for attacking issues.
