Turn signal blinks for a short while then stops

When I push my turn signal lever, the lights come on and sometimes, it blinks for a few seconds and then stops or some other times, the lights come on, but they don't blink at all.
I suspect it could be the turn signal relay, but I have seen other people say it's the flasher. Can you tell me the difference? Also please let me know where to find the relay or the flasher in the car. Thank you in advance.

Hello,

It does sound like a faulty flasher relay. The turn signal relay or the flasher are the same part.
This is likely to have too much internal resistance and gets hot and stops working.

This is located under the dash, just right of the steering wheel.

I have attached a diagram showing its location.

Please let me know if you have any questions.
Thank you.

I went to look for the Flasher relay and found it behind the dashboard on the driver's side. I think in touching it, I must have jiggled it a bit because it started working without stopping. I'll watch it for the next few days and see if it continues working correctly. Even if it fails, I know where and what to change now. Thank you very much.
