My rear windscreen wiper won't work - what's the issue?

My rear windscreen wiper stopped working a week ago and I'm worried it will cost me a lot if I take it to a garage. Can you advise what the problem is? I'm guessing it has to do with the wiring but I'm a novice and don't want cause bigger damage.
Might be the wiring loom to the motor that passes from the car body to the hatchback and is vulnerable to the cables wearing and breaking. Might be the motor itself. Best to get a local electrical specialist onto it.
