Check the bulbs. This usually indicates you have a bulb out. In fact, it is a handy signal that you have a bulb out. The 4-way flasher has more bulbs to power, so it doesn't notice that one is missing.
if indicator flasher is signal relay then its underneath dashboard, driver's side..
Turn left indicator signal flashes rapidly when I use indicator, bulbs ok, no lights working
have a friend stand in front of the car and look to see if it flashes or not
Flasher relay is defective.
Access indicator flasher under instrument panel left of steering column. Remove screw retaining indicator flasher to instrument panel. Disconnect connector from indicator flasher and remove indicator flasher from vehical. I am also trying to find flasher on 1997 t bird. I hear it but cant find it- Help please
Test the flasher or just replace if not expensive. replace the flasher can usually found near the fuse box
if it only flashes fast on one side, you have bulb out on that side. If both sides are fast, change the flasher
Make sure all bulbs are working Replace turn signal flasher
Generally, this means that a bulb is burned out, or that your flasher has died. If you only experience the problem on one side, in other words, left signal only, or right signal only, you can pretty much count on it being a bulb. If it's on both sides, it's probably the flasher. FriPilot
How bout the turn signal indicator switch located in the steering column.
Bad flasher.
