Turn on that fast blinking signal light and check to see if the front and rear signal lights are both working, chances are you have a burned out bulb. If both front and rear bulbs are flashing fast, replace the flasher relay.
Answeri got the same problem.. with a 2000 expedition... darn theft light blinks real fast and the car wont start. help!
Most likely because one (or more) of the signal light bulbs is burnt out from the fast flashing side. Check them first, replace the burnt bulb, and they should go back to normal. If there are no burnt out bulbs, then you might consider replacing the turn signal relay.
The bulb that is not illuminating, is installed incorrectly. Take it out, and replace it with a new one, making sure the nubs on the socket are in the right slots.
Check all of your turn signal bulbs. One of them may be burned out.
A fast flashing light means your turn signal flasher is about shot. It's a simple fix, usually under $6 for a new flasher, depending on the vehicle. Just pull the old one out and stick a new one in, it's just like a big round (or square) fuse. If you can't find the flasher, turn the signal on and it will be clicking away in the fuse panel under the dash.
I would look at the REAR signal light on the same side of the car. It is probably not blinking at all and the bulb needs to be replaced.
A light bulb needs to be replaced. The signal is fast because the electrical current is there, but since it does not turn on the burned out bult, it makes the others work twice as fast.
One of the bulbs is out. Replace it.
The new bulb is already burned out, not seated properly in its socket, or you replaced the wrong one. Get out and look at the signal lights while they are blinking fast. Either the front or rear light is not blinking at all. That is the one that needs to be replaced.
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
A signal that is blinking fast usually indicates a bad bulb or bad flasher. Check to insure all of the bulbs burn, then check the flasher.
It probably means that one of your head or tail lights is about to go out. I have a Ford Taurus and my right blinker started blinking very quickly and within a week, my right headlight was out.
i think one of your bulbs in another light are out. mine was blinking fast only on one side, so i checked them and replaced the burned out one and it blinked normal again.
It means that the light is about to go out. For example if you turn on your right blinker and it is blinking fast it means the light is about to go out and you should change it.
A bulb has burnt out that is why it is blinking fast. Check the front and rear bulbs.
This is probably due to a faulty relay switch. The switch needs to be replaced so it will blink in the right timing.
Its probably a bad flasher or sometimes a bad bulb can cause that to happen.
