I have a 2006 VW Golf and the internal fan motor that blows the a/c & heat will start to 'chirp' (sound something like a bird singing) randomly.
I believe the fan blade needs to be lubricated, but I have no clue how to go about accessing the blade's location since it is somewhere inside the dashboard.
Is there any way to spray something like WD40 inside the air intake for the ventilation system to calm the chirps?
