It's a $9 part at any NAPA, Carquest, etc. Stealership is going to charge you a small fortune for a generic part. Take your stock one into the parts store and match up the terminals. Not likely the problem but...
They do go bad. Can be stuck in a no power or constant power mode. Usually no power, but all it takes is a bit of water to seep in, cause corrosion, and bridge the internals. The bike version is smaller and more weather resistant than the old fashioned car canisters but are still subject to the same issues. Vibration, moisture, poor internal connections, etc.
Are signals required where you live? Down here everybody ignores them, the state dropped the mandate for bike turn signals in 2005, regardless of the model year.
I'm not sure if you've ever worked on the flasher in this bike but the flasher is always getting and supplying power. The reason the signals aren't on constantly is because the switch on the handlebars is off.
The circuit goes like this:
Battery-> Flasher-> Switch-> Signal-> Ground
If the flasher goes bad there are only two things that can happen:
1) The signals don't blink
2) The signals don't turn on at all
