The problem I'm having is that when I switch on the headlamps the dashboard and tail lights should switch on at the same time, the problem being that the dashboard and tail lights do not come on.

I've checked that I've actually switched the said l0ights on, I've checked ALL of the fuses both under the bonnet and in the cabin.

Its worth pointing out that the actual headlamps and the brake lights DO work which has caused me some major confusion as you can imagine.

There can't really be any night driving until I get this problem sorted.

If you require anymore information just let me know.
