Indicator not working left side

[Overknasten]

Hi again.
Suddenly my left side indicator lamps stopped working or to be more precise the front left indicator. The side and rear works in a slow way and then it dies. There is no indicator sound from left side anymore
The right side works well.
The front lamp is fine and all connections should be OK.
Is it in the stalk mechanics and where is the relay, if any?
I can here the clicking (when trying the right side) but can’t locate any relay.

The relay should be below the dash, near the steering columm, in the neighbourhoood of the choke lever.
