Yep, a bad bulb is the most likely cause.

I'd have to look in the manual to be sure, but I don't think the C5 has a flasher (little can under the dash). Blinking should be controlled by the BCM. That's the case on a couple of my other newer cars.

there is a DIY section on the forum to replace flasher relay switch.

Do you drive the car a lot or does it sit inthe garage for extended periods of time? If it's a "garage queen" the blinker fluid may be old and should be changed and the system flushed. I saw post on here the other day with more info on a blinker fluid source but now can't find it. Maybe someone else knows where it was.
And don't waste your money on the OEM fluid. Amsoil and Royal Purple both make fluids that not only give smoother blinking but increase blinker life by at least 12% (according to testing) and improve fuel economy because the electrical drain is less and thus the alternator doesn't pull as much horsepower from the engine to drive the charging system which reduces fuel burn, even at idle.
Or, it could be a bad blinker. I associate very slow blinking with a bad bulb, but that was back in the day before the development of extended duty, all-synthetic blinker fluid with 50,000 mile change intervals instead of 5,000 miles.
I'm having too much fun with this and it's time to get ready for work.
Seriously (finally), it's probably the flasher.

Believe it or not, your on board computer senses voltage, and goes into "rapid" flash if it senses low voltage - like a bad bulb or LED lights (which draw less voltage). The fix is easy 1. replace a bad bulb. or 2. If you have LED's replace your hazard flasher with an LED flasher unit (not cheap) and all will work normal once again!!!!!!!!!!!!!
