Technical Indicators not working

[mortirolo]

Multipla indicators, suffering with failure to work when the car is cold, after vehicle has warmed up... 10 miles or more, indicators start to work:bang:

Any suggestions

I have to say that I'm like that these days

Possibly an earthing issue, where would I look on the vehicle to check if the wiring is earthed correctly?
