Hello,

Just to cover the basics.
This vehicle has the 3 flashes to pass/change lane turn signal.
It gets triggered when the turn signal gets pressed lightly. It is designed to turn off after 3 flashes.

To fully engage the turn signal you will have to press the lever further up or down, it will click in to position for the desired turn.

As you release the wheel after the turn the cam in the wheel will cancel the signal.

Now if the issue is that the turn signal lever engages/clicks but then cancels out by itself. Then it is a faulty switch and will need replacing.

Please let me know if that is what you are experiencing.

I have attached diagrams for your reference.

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