Just started this morning, Hazard is clicking away. I ordered the turn signal. I read that most guys start out with the hazard switch and end up replacing the Turn signal stalk. So thanks to those posts I'm going the other route.

Do you think I will need the hazard/signal relay also???

 

If I were you, I would buy the hazard relay just to err on the safe side and have the part on-hand if the signal stalk turns out not to be the culprit.
Didn't/don't have problem with mine and you also have the C5, so I wouldn't really know what's the best advice in this situation.
What's the relay for your car, $ 40-60?

 

Thank's Chefro.

I'm certain this cold weather is to blame. My poor Florida car must be wondering WTF is happening!!!

I must say... Did a few donuts in the snow the other day

 

I hear ya! Mine snapped out of it rather soon after the initial bitter cold shock, and got with the program.
She's somewhat melancholic though: even after two good years I still find Florida sand here and there. LOL

 

Mine got so bad, the signal lights wouldn't work. I replaced the relay, then the signals worked, but the relay still clicked. So i think in my case it was the stalk that caused the relay to click, and because i left it, the excessive cycling of the relay caused it to burn out and signals not to work.
