I HAVE NO TURN SIGNALS NOR FLASHERS

I have no turn signals nor flashers. I have all running lights working. Sides front rear etc. I have replaced all bulbs. The brake lights work. They did not prior to everything not working, but after replacing the bulbs (original and the contacts had wear but the filament appeared fine) they work now. All of the fuses are working I have checked by use of a test light. I have replaced the flasher relay. To the left near the steering column, as well as the multi function switch. Still I have no flashers nor turn signals. The indicators in the dash do not light up. The lights do not work. I have also removed any grounds for the side markers and front lights and cleaned them. And used dielectric grease on all connections.

I saw someone post a diagram and test procedure for the plugs on back of the multi function switch. It was a FSM diagram. Maybe that would help. Or any other ideas? One turn the signals worked the next they did not. No burning smells etc.

Do you

Short answer is yes. There is not a flasher fuse behind the glovebox. There may be one In the power distribution block In the engine compartment. Though it is just numbered if there is one. So the turn signal switch fuse has power to both sides of the fuse. Every fuse in the jeep has power to both sides. Including the switched and non switched fuses.

And both the flasher relay/ flasher and the multifunction/switch replaced

Go to the turn signal switch with the key in the run position with the turn signal switch in the left position you should have power at the dark green wire with a red stripe?Then with the switch in the right position you should have power on the brown wire with a red stripe?

Alright key still in the run position see if the pink wire has power to it at the multifunction switch? Then with the turn signal switch in the right position the tan wire at the multifunction switch should have a flashing power?Then with the switch in the left position the dark green with a red stripe should have flashing power?Check these wires with a test light.
