Why are my turn signals blinking real fast in my c5 corvette even though all bulbs are replaced and work just fine?

Fast-blinking turn signals in your C5 Corvette, despite having all bulbs replaced and functioning, typically indicate a problem with the turn signal circuit. This could be due to a faulty relay, a poor connection, or a grounding issue. Additionally, ensure that the replacement bulbs are the correct type and wattage, as mismatched bulbs can also cause rapid blinking. Checking the wiring and connections for any damage or corrosion may help resolve the issue.
