Mazda 2 - rear right indicator stuck on; how hard is it to replace the relay?

Hi, first post.

My wife has a 55 plate Mazda 2, and I got a call this morning from her to say that the right rear indicator was stuck on. Managed to get it to go off by turning the hazards on and off, but I guess the indicator relay is on it's way out.

I assume it's not a very tricky job to do, but can anyone let me know where the relay is on the car and, ideally, the part number?

Of course, if it could be something other than the relay (esp. as it's only one indicator that's stuck on), feel free to tell me.

Appreciate any help, thanks.

It should be the relay. I'm not sure where, but the user manual should say. My guess is its one of the ones in the engine bay box.
