your problem could be a bad bulb (front or back) or it may be a bad flasher cube which is located usually where your fuse block is. hope this helps. good luck
Replace the signal flasher relay assuming you have physically seen front and rear, left and right signal bulbs flash.
Usually when ones turn signal is blinking fast its telling you that a turn signal bulb (and in some cases a brake light bulb) is out. If it blinks fast when you turn on the the left signal the burnt out bulb is on that side of the vehicle (could be front or rear bulb so you'll have to check). And vice versa
Defective turn signal switch.
Usually if the signal is blinking fast, it means there is a problem with the circuit. Usually this is caused by a lightbulb going out. They've engineered the cars to blink fast to let you know that the bulb might be out, since you usually can't see your own turn signals. I'd try replacing the rear taillight bulb first to see if that fixes the problem.
It is possible one of the left side light bulbs is burnt out. A burbt out bulb will cause a higher current to pass through the flasher component and the flasher will rapidly cycle on and off.
If you turn on your 1999 mustang v6 car and the right signal light stays on and doesn't blink and you switch the car off and then the left signal light stays on without blinking, then you need to see a mechanic.
u need to replace both bulbs
the turn signal switch in the steering column
One of the bulbs is burned out on the left side. The left front or rear bulb is burned out. Same problem with left side blinking rapidly and right side blinking normal speed. Both left side bulbs are lighting up, however?? Replaced both anyway and the problem still exists.
My 1997 Honda Accord was crashed into a snow bank, broke front left turn signal light(Bulb+assembly). Soon after the crash, the rear left turn signal began blinking rapidly. Several days after, the whole turn signal system shut down (all four blinkers stopped blinking). I replaced the bulb+assembly for the left, turn signal switch, and turn signal relay and checked the fuses. The hazard lights work, but the turn signals don't. I did everything I could replacing parts. Does anyone know what is wrong with my accord?
It means that a light bulb is out on the side where the light solid (not blinking) it could be in the front or rear of the vehicle.
More than likely you have a burnt out bulb at the front signal light, rear signal light, or brake light on the right side.
