Nothing happens when i use the turn signal lever, no lights or turn signals, nothing clicking, just nothing

possible flasher unit, in or near the fuse box.. does click sound when you push lever up or down, also if emergency lights do not flash but come on then first thing to replace is the flasher unit.. not very expensive and easy to replace, after that it is possible the signal lever is bad.. more involved work but can be done.

reset the computer throw diagnostic port .

there should be a fuse for the direction light. and a direction switch can be bad and still click and operate as it suppose to

This sounds like your turn signal relay is sticking. If it is sticking it does not matter the position of your turn signal arm. Check the relay. It will be in your fuse box under the hood.

Pull the steering wheel and clean the turn signal switch and look for broken parts. If that doesn't fix it, then replace the turn signal wand on the steering column.

I would try replacing the flasher first if that doesnt help then i would say there a problem in the signal light switch, this means the signal light switch needs replacing,

I Think your turn signal switch is most probably faulty. So that, you will need to replace it. Please, check the video below. It shows the operations to replace the turn signal switch. I think that the operations are quite similar in most modern cars. Good luck!

either the lines are grounded or the lever on your steering wheel is stacking up

First check the fuse, then the flasher. If it still doesn’t work you will check the relay. Finely and more difficult is the turn signal switch. This involves removing the steering wheel.

Check the flasher under the dash to the left of the steering column. It's got about 8 or 10 wires plugged into it.
