Turn signals work sometimes, sometimes they don't

Flashing too fast means that at least one exterior bulb isn't working. IF its an intermittent problem, once bulb could not be making connection at times. next time its flashing fast, stop the car and look to see which bulb isn't working. Replace that bulb, clean the socket at the same time

you don`t say what kind of car you have. there are turn signal cancelling lobes on the turn signal switch and sometimes they are cancelling springs that are pushed back when turning to cancel the signals. sometimes they break and require replacing, sometimes you have to replace the signal switch itself.

Multi funtion switch is shot,

I would guess lose connections or blown fuse

either you have a loose bulb or there is a short in the wiring harness for the turn signal.

I would guess that the turn signal switch is worn out

You said they work some times,so the flasher is good

You need a repair shop i assume

You didn't meantion your expertise in
troublshooting electrical issues

sometime the combination switch can cause this problem , alot of times u can turn your hazard lite switch on and off a couple of times and the turn signals will go back to working ,
