HELP! The first REAL problem with my Stang...

[Hammer]

Well, I was sitting in my yellow 98 GT waiting for a chance to make a right hand turn with my trusty blinker on....

Then an almighty gremlin attacked, I heard a click come from the right side of the dash, and my right turn signal started to go on and off TWICE AS FAST! The right signal still works (just faster), and the left turn signal and emergency blinkers are still normal. No smoke or any smells to indicate a major electrical problem....
Now I know a lot of rice boys would die for a free mod like this, but does anyone have an idea of what it might be before I take it in for warranty service?

Thanks...
