Hazard lights flash when right turn signal is flashing

[Tony49]

When I turn on my right turn signal the rear hazard lights also flash.
The front hazard lights do not flash with the right turn signal on.
The left turn signal works normally.
All the hazard lights work normally when the hazard light switch is pushed on.

Sounds like a bad earth to the light unit.

May have to replace the turn signal stalk ?
