Hello,

A couple of weeks ago the blower fan stopped working in my Fabia II. Just before, it had made noise which made me believe that the motor had packed up. I ordered a new fan and had a mecanic change the old one. This did not solve the problem. The fan is still silent!

The car has the climatronic system. I have managed to measure the power two the blower motor (disconnected the terminal at the motor). At zero speed on the climatronic display the power is 11-12 V. At full speed it is slightly higher, maybe 0,2 V. I have tried to run the old motor directly on the battery and it spins even though the resistance turning the fan by hand is obvious.

The fault code i get is "01273 - Fresh Air Blower (V2)". If I set the fan speed to zero on the climatronic display I manage to erase the fault code. If I keep the speed to zero the fault code "stays away" but when i "start" the fan on the display, soon the fault code comes back.

I start to believe that it is the "fresh air blower control unit -J126-" that has packed up and that the fan has never been the real problem!? But why does the new fan not spin as it has power. To me it should spin even with the fan speed set to zero as it has 11-12 V.

 

Any help to solve the problem is much appreciated  .

Did you make sure you had the correct new fan? The climatronic uses a different fan and resistor to the climatic system and is a dash out job to swap. (£400-£500 job). If the fitter says he did it and did not take the dash out, he is most likely lying and tested things, thought it worked and swapped something else. The issue is, as you got the part, he only fitted what you offered up so if it was not the fault, though! 

There are quite a few other possibilities so getting a proper VAG known g mechanic and not a local back street tinkler is a preferred option. 

Had this in my old fabia, because of the air con glove box is the reason the whole dash has to come out. I was told it's an easy fix if it's a normal glovebox but because of the air con it's a sealed unit

it could be a fault with the resistor pack, test the motor vltage with the fan connected and see if it is stil the same, if there is no power it will be the pack

Climatronic has built in resistor, its not the same resistor pack that the climatic uses, where you can swap it via the glovebox/airbag aperture.
