My turn signal blinks once when I click it and then its done blinking..... I had this problem a month or so ago and it fixed itself after a few days of not working. Now its been about a week since it stopped working again. I have no idea whats up.

 

Just one side or both?
If it's one side only it's likely just a bulb.
Both side you might need a new flasher unit.

 

Both sides. and I know I changed something when they didnt work at all.....might have been the flasher unit....no sure

 

i have a problem like that with my left turn signal i went over a curb and it turned back on but after a while it stopped working again do i need to replace the flasher or the bulb?

 

So...Nobody knows?

 

either a bad connection or the flasher is bad. change flasher first.

 

And when you change something, write it down so you know what the hell you did.
Trust me, your memory won't be getting better with age!
