Flaky Turn Signal

[RWBitters]

I'm hoping that someone might have seen this problem before, or might be able to give me some advice.

Eveything is working just fine on my 2003 GZ250 except the turn signals. The turn signals work occationally, like one out of every ten times I try. Here's what I've noticed:
the left one is more likely to work but does not always work. The right one is less likely to work. When they do work (in either direction) they are likey to work the next time I use them. When either one fails to work, they are both unlikely to work the next time I try. It's totally hit-or-miss when I use the turn signals. I also found that this behavior is the same regardless if the bike is moving, standing still idling, or with the engine off and the key in the on position. Leads me to think that it's probably not a loose wire since it behaves the same when the bike is motionless.

Anyone have any ideas about what I should look at? Could it be the switch itself? Could it be the turnsignal/sidestand relay? Anyone have any other ideas or a good way to diagnose it?

I'm now starting to use hand signals, becasue my arm is a way more reliable indicator to others of the direction that I'm headed. I need to fix this so that I can take it to state inspection. The inspection is way overdue and it will not pass if the turn signals don't work.
