Blinker mania

I have never seen this before on any other car, my passenger side blinkers work. They blink at normal speed for the first 3 - 6 blinks, then it speeds up. It never set the light bulb error either. It speeds up noticbly buy not like the drivers side. The driver side blinkers all work but they blink vey fast, this is like a bulb is out where as the passenger side is about half way between normal and bulb out.

The drivers side always triggers the bulb error light, even though they work. Any insight would help a bunch.
