Turn signals on!

Hello, I have a volatile phenomenon, but it doesn’t stop every time. if I press my flasher no matter if left or right, it doesn’t blink, but the flasher just lights up until I take out the flasher. I assume that it is on the relay, if yes, where is the flasher relay?? A small question I would have in addition. If the cam crankshaft sensor has so slow a blow away, and the engine does not start now and then, then the motor control light lights up?? With the antenna ring nothing should normally light up. With me nothing lights up if the engine doesn’t want to start. I know that from other car manufacturers that lights up the motor control light when the cam crankshaft sensor has a blow away, so I ask, because then I know where I have to start looking. Because in addition, I have the problem. Before I forget it, it is a C70 2.0 year 2000 Thanks and a nice weekend!
