Turn signals died

Sinse you have two flasher units you will have two separate power supplies.
So that tells me that the flasher's will work with the ignition off.
And the turn signal circuit needs the switch on.could it be a circuit that leave's your ignition switch.
Are you checking for 12 volts or continuity?
I am shur you have checked for a fuse but is there a fussed link under your dash leaving the steering column.
Let me know if you have figured this out and I will look for a wire diagram this morning. :coffee2:
