My emergency flashers and blinkers aren't working. Fuse and bulbs are good
Have you check the switch to see if it is good?
I replaced the relay switch too.
By "relay switch" I assume you meant the plug in relay mounted under the dash panel. There may be 2 relays - one for the flashers and one for the emergency lights. Look for a second relay before going any further.
