Hit it. Hard
Reset the light. Turn everything off. Turn the key on and off when the light just goes off. Keep doing this several times, the light will reset
The security light will blink when either door, hatch, or hood is opened and will continue blinking until it is closed. Check all 4 switches for proper operation. If the bad switch is disconnected it should turn off the light. If the security light is on constantly instead of blinking that is to let you know that the alarm system is activated and should turn off after a few minutes.
It is blinking by a lamp first turning on, then turning off, then turning on, then turning off...
check brake fluid level.
That means its broke.
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.
The light is blinking on and off because there may be a problem with the electrical connection or the light bulb itself. This can be caused by a loose wire, a faulty switch, or a flickering bulb.
Turn it off and let it cool. Unplug it from the outlet when it is off, and move it to a place with better ventilation and clean the air vents.
You have a broken spring in the steering column
If it's just one way and it wont shut off then its probably just to turn signal switch.
The lights are blinking on and off because there may be an issue with the electrical connection or a problem with the light bulb itself.
I tried holding down the trip odometer button and starting the car and holding it until the light stopped blinking.
