Leave car outside during hailstorm

Like he said.
It means one of your left blinker globes is out.

Stop driving German/British vehicles

Did you check your blinker fluid? It may be low...

If all the lights work and it's still blinking fast, that means one is about to go out. I'd replace both one at a time to see which one it is.

Sometimes my blinker just lights up it doesn't blink. I manually make it blink for a bit until it starts blinking on its own

It's been doing this for 3 years

Replace the broken bulb fuck head

Try replacing the flasher. It's under the driver side of the dash, you should be able to grab one from the junkyard for a couple bucks.

I'll give it a look tomorrow. Th-thanks

Just started happening on my car day before yesterday. Communist hacking?

I had this happen on an old Mazda, I had to jiggle the stalk a bit for it to work. Problem fixed itself after awhile*shrug*
