Turn Signal Indicator blinking fast

[gbuydos]

My turn signal indictors on the dash just started blinking fast when activated. All the actual turn signal lights are working. What could possibly cause this.

I have had an issue with blind spot assist and rear parking sensors. Are they all tied together?

Take your "Lightening" to the dealer and let them deal with it. Perks of a new car with a warranty.

If your Ford Lightning's turn signal is blinking fast, it usually indicates a burnt-out turn signal bulb on that side of the vehicle; the faulty bulb disrupts the electrical circuit, causing the rapid blinking as a warning that a bulb needs to be replaced

I agree, but taking the car to the dealership is a pain in the ass. Sometimes, with the help of these forums, this is a known issue and the answer may be a lot simpler that a torture session at the dealership. Just trying the simpler path first.

Its odd that both right and left would go south at the same time. I replaced a tail light over a year ago with a used one from eBay and it hyper-flashed. The other one still acted normally. Seller refunded my money. Got another used one and it worked.

I agree - dealer issue at this point. You can disable it in FORScan but wouldn't recommend it.

The blind spot sensor is in the tail light.

12v reset will fix it

I had the same and noticed that one tail light was out and had some condensation in it. dealer replaced it and it fixed the issue

I've had this with a burnt out bulb on a trailer. All lights on the truck were fine and it returned to normal when trailer was disconnected. Any chance you've connected something to the trailer electrical port?

My left blinker double flashes when the temp is above 60 and the front light blinks white, not orange. It works OK when it’s cold out. Dealership has no idea, seems I have to live with it.

Hilarious. Does the AI know these are all LEDs?

Did not try yet. We had an ice storm, so most likely this weekend.
