Hi, I just bought used Skoda Fabia 1.2 TSI with Climatronic. 

Does anybody know how to fix the airflow button from Climatronic?
Light does not work and the button does not move at all.

I tried already to clear the button underneath but there wasn't anything, I think the issue is deeper.

I tried to remove the button but it is very tight and I feel like it can break.

Remove the whole panel (as far as I remember there are no screwa so just pull it out) and then you will be able to have it dismantled and cleaned. In th eworst scenario yu can but a second hand one and replace it by yourself, its not covered with component protection.
