Turn signals and 4way have stopped working,changed relay,no luck. Does this mean the column switch has died?

When you use the turn signal lever does the indicator light on the dash turn on?

The only other thing common comes to mind is the multi- function switch on the steering column. It interrupts the power to the selected brake/signal filament in the front & rear bulbs to do flashing. If not interrupted, the power goes through this switch to both brake lights. If you manually move the lever to a 'signal' position, do the bulbs light on the dash and in the F & R lamps? That generally checks the cause being the flasher or the switch. If they do nothing, then the switch is not doing anything to the power flow. If you have no brake lights, the switch might be cutting the power completely, but I would check the switch on the pedal arm to be sure. If you get the EVT manual, it will give specific test you can do on the MF switch to determine if it is functional or not. It is not difficult to replace, just a bit pricey.

No, no indicators lights on dash, only function of switch that works is bright lights, high beams come on and dash lindicator comes on
