The turning signal on my 1998 Hond Accord flashes rapidly. Check the bulbs and fuses, they all seem to be OK. Only on the signal on the instrument display area flashes rapidly. What might be the problem?

Rapid flashing usually means a bulb is open. Double check all the bulbs and let us know.

Not sure the year flashers changed. In the old? Days if a bulb blew, you would get a slow flash, or no flash, a short or heavy load they would flash quickly. The newer ones flash quickly if bulb is blown.
Turn on you 4 way flashers, walk around vehicle and verify all bulbs are working.
