Sounds like you've lost the ground connection to that light. Identify which of the wires is ground and run a temporary ground to verify.
Have vehicle scanned to determine problem
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.
Answeri got the same problem.. with a 2000 expedition... darn theft light blinks real fast and the car wont start. help!

There are pages and pages of things that can cause a check engine light. You need to have it checked with a scantool. Then the code can be diagnosed and repaired.
An L.E.D blinker is an L.E.D light that blinks on and off.
If it blinks fast either one of the two lights are burned out or the relay is failing
turn it off, awww this is the mon
If it is not blinking at all or blinks too fast, one of the bulbs is burned out.
change the bulb out for the brake light and that fixes the problem.
Turn signal flasher may be defective
That means it time for a new blinker light it is burned out.
Usually one of two things happen when the resistance of a blinker circuit changes (as would be caused by, say, a bulb burning out or a short in the circuit): either it doesn't blink at all, or it blinks really fast. So the first thing I'd check would be to make sure that the bulb is lighting the way it's supposed to.
Check bulbs Replace flasher
Check the ground, without a proper ground it will not light up
One of the front blinker bulbs is burnt out. Replace the bad bulb and the blink should function normaly. you have a front right turn signal bulb that is burned out. the resone it blinks fast is there is less load on the flasher .
If you are referring to the blinker indicators on the dash board, it is because one the signal light bulbs need to be replaced. The side that blinks faster is the side where the bulb needs to be replaced. Turn the blinker on and walk around the car to see if it is the rear or front bulb that needs replacement.
