Tame Technician; fan blower problem

[bn9af]

Audi A3 3.2 2005 plate with climate control, the fan blower has stopped working, first thing checked the fuses, they all seem fine. Problem is that no matter where you select the fan to blow, no air comes out even with the fan on full speed.

Since the fuses are ok i think the next thing to check is that the fan has power going to it, could you please tell me where its located?

Logic being, if the fan has power going to it, then it must be the fan that is broken, but if there is no power then there is a fault somewhere else!

Fan is behind the glove box. But might be able to access the connections for testing without removing the glove box and instead, just take off the soft trim under the glovebox in the footwell area.

Could be missing signal from the climate control module, but much more likely the blower motor control module is dead. Cant remember exactly what there like without looking, but 99% sure will look like a heat sink and is bolted to + wired to the blower motor its self.

ok thanks i'll have a play at pulling trim off tomorrow, see whats what.

If it is the controller, how much are they roughly?

Update: took the glove box off and one of the connectors had worked loose, so clipped it back together and cable tied it for good measure. Fans work again, nice and cold and managed to cure a slight rattle from the glove box in the process of removing and replacing it!
