Thanks mate i will try your suggestion with the dashboard, i think i have made a small breakthrough on the issue, it's localted on the plastic part on the right side of the air vent, i have attached a short clip showing that when i poke around on the right end there is a buzzing noise, can this plastic part be taken off without the dissasembly of the whole dashboard? Here is the clip - > https://youtube.com/shorts/ezEg2t5xhNE
