Hi everyone. Today all of a sudden my left turn signal started flashing really fast like there was a bulb burned out, checked and they are working and blinking really fast. Any ideas....Thanks TR

This is assuming you're using proper incandescent bulbs and not LED's.

If it's only the left doing that then it's most likely a bulb issue, either the front or the rear ones. Replace them all and see if that resolves your issue.

If the right is also flashing fast, then you'll need to replace your turn signal flasher.

If replacing the bulbs and the turn signal flasher doesn't work, then it's a low voltage issue; most likely ground issue.

 

Thanks, been the same bulb for 14 years. All lights are working (parking, brake, 4 ways) so i dont know what else it could be. it isnt bad just annoying that something is different than it use to be.Quess i will just wait and see how it plays out. Thanks again

 

Simplest way to test is to replace the bulb and see if that fixes anything at all. Keep us posted on if you resolved the issue or not in the future.

Peace
