I have a 2001-c5 corvette and am having problems with my turn signals quiting and then starting again. Has anyone had any problems like this or do you know if there is a flasher unit that can be replaced? Thanks, Dave

 

I believe there is a flasher relay that goes bad frequently on those models

 

cycle the haz.switch a few times

 

The Hazard switch (by the center air vents in the dash) is known to be a problem in C5s. The "normal" turn signals are routed through the hazard switch and when it goes, your turn signals become unreliable.

As extanker mentions, you can cycle the hazard switch a few times but the problem will become worse with time. The best fix is to replace the hazard switch (my 2002 Z06 had this problem too).
