More recently the clock display started to randomly not come on and now it never comes on any more (light and LCD):

At the same time the parking sensors started to beep continually when in reverse.
Now that the clock is failing the parking sensors seem to be working again.
Does anybody have any idea what is happening? I could try replacing the fuse but I have no idea which fuse is which in my car.
I am happy to get my hands dirty if needs be.
