Why would the turn signal blinker stay on after the signal is canceled and the light is off?

If it is a 1999 is could be because of this: The only continuing problem is this: most cars have a few items that are typical failure points, and we've found one. The combination switch (turn signal, cruise, wiper/washer, flasher) on the Blazer is at the top of the list. We've found that it's very common for the flasher relay (under the dash, right side) to start clicking endlessly and audibly while no lights are flashing. Turns out the Blazer's combination switch is the problem. It's usually either failure in the turn signal stalk, or contact problems with the emergency flasher switch mounted on top of the steering column. If you remove the shroud, you'll find the switch assembly and turn signal stalk must be replaced as a unit.
This problem is so common that it's a topic of discussion on Blazer and S10 discussion boards, but don't expect a dealer adjustment. If it happens to you, expect to pay for a repair. In some cases owners have been able to spray generous amounts of contact cleaner into the switch and stop the relay clicking, but it's a very hit-or-miss proposition and you have to be lucky to avoid replacing the switch. However, if this is the biggest problem you ever have with the vehicle, life isn't that bad!
Condition: Used
Model Year: 1999
Model and Options: LS, 4-dor, 4WD Some have said it is because the grease used to lubricate the switch was "conductive" instead of "dielectric" If not a 1999 it could still be a bad "combination switch" in the steering wheel but for normal wear and tear

The right tail light and signal blinker work on your Toyota highlander but the right brake light does not How do you fix the problem?
Hmmm, kind of unusual because the same bulb filament serves BOTH the blinker and the brake function. It could be a short in the wire from the brake switch leading back to that particular bulb and if the left brake light work okay it would have to be somewhere AFTER the wires leading to the rear lights branch off from one another. Are you CERTAIN that the right rear signal blinker DOES work?
How do you make my turn signal blink faster?
Why would you want the blinker faster. They should blink at factory specs.
Why does the left signal light blink so fast on my 1999 cadillac deville stop working now right blinker want work either?
sounds like an electrical fault i would take it to a mechanic
Why would your turn signals not work on the rear of your truck when the headlights are on?
Generally, the tail "light" and the tail light "blinker" are two different bulbs. Check the blinker bulb first. If it is OK, then it is likely a fuse to a flasher unit.
Why would your wont your turn signal work but your hazerds will and i replaced all the fuses?
Could be the control stick for the blinkers. If the lights work, try replacing the stick or checking out the signal path for that blinker
What would cause a signal light to work sometimes?
I have a 2000 olds alero and the signal light only work sometimes, What would cause that?
Why would the left turn signal indicator stop flashing and indicator light?
You have a turn signal light-bulb out .
How would you fix your blinkers if it isn't the fuse and they don't work manually by hitting the blinker arm?
If you are saying you have to manually turn the blinker on and off by hand, then the flasher relay is bad. If you are saying you have to hold the turn signal lever in position and it does work and flashes on and off by doing this, then the turn signal lever is broken inside and needs replacing.
What would make your blinker lights stop working in a 96 crown vic?
Your light has gone out or a bad fuse
Why would the blinker not light up if the bulb is good and the fuse is good?
Check the relay. Turn signals work off of a flasher. Replace the flasher they are usually cheap. If that does not fix it check the signal switch. That is the thing that you use to turn on the turn signals. That is usually the problem.
What fuse do you check for a turn signal on a 1990 Buick Lesabre?
If the signal light fuse is blown all the signal lights front and rear would not work. If you have one signal light out I would first suspect a bad bulb or bad connection.
Why would my blinker blink once and stop on a 2001 vw passat?
Usually a bad turn signal flasher Check to make sure all bulbs are working I had this problem. Had to replace the hazard warning light switch in the dash. 1999 Passat 1.9TDi UK spec.
