4-way Flashers not working

Thanks. I will try to locate the 4-way flasher later today.

What vehicle?

Have you replaced any bulbs outside the coach in a while? If so I would pull those bulbs and see if the problem goes away.

If the bulbs are good I would look at the flashers. There are usually two flasher units in a vehicles. You have already replaced the turn signal flasher. You need to find and replace the Hazard light flasher.

how 'bout the 4-way flasher?
