Turn signal not working

Try lubing hazzard switch. It interacts with turn signals. Or just replace it? You also may have a bad multi sitch which is your turn signal assembly. Could be wire loose or bent contact, etc.

All blinkers or just one? Do they work in reverse? Neutral? Do the hazard flashers work in drive?

Ashwome,

Has an inspection been performed that found a wiring problem? If that is a shops diagnosis, ok; however, the common failure for this problem is the turn signal/hazard flasher mounted in the center of your dashboard.

Next time your turn signals don't activate try rapping firmly near the hazard button, preferably above it without actually touching the switch. The relay contacts often fail and may reconnect from the bumping. If this is symptom, I recommend taking it to a dealer that has performed this repair before. Removing the center vent and two 7mm screws is difficult without damaging either component.

When it doesn't work, do any of the lights come on?

It sounds like the switch itself is bad. I would check that first.

Is the buzzing coming from the switch or under the dash?

Try replacing the flasher. It could be the problem.

Let me know what you find. The flasher is a cheap part.
