Blinker lights and emergency flashers

[Steve barnett]

The exterior lights work, but the blinkers and flashers do not work outside or inside on the control panel

Check the plug going up the steering column and make sure it's clean and tight.

You could have 2 flasher units under the dash. One is for turn signals and the other for emergency flashers. I do not expect these to be combined. On my coach it is a cylindrical unit about 1” in diameter and about as tall connecting to 2 wires. 
Get under the dash to find and remove it. As Tim said check that is correctly seated. If it is still not working, you can get a replacement at any auto parts store for less than $20.

Thank you who all answered my request I found out it was the plug on the steering column. The clip broke and it vibrated out so I connected it back and everything’s wonderful. Thank you very much.
