Blower removal without dash removal - Ibiza Mk4
I think to get the fan motor out you have to remove all the dash and start removing the metal frame work round the motor before it comes out. Ive never done it before so Im not in the know of
how to do it. Possibly shows it in the haynes manuel for our cars ?
That's what the Haynes manual says. However, it is actually possible to do it WITHOUT removing the dash. I've just done it. I had a dead fan, thought it was the resistor pack (actually a thyristor controller on the Climatronic cars), but stupidly didn't check the voltage at the fan first - really dumb, I know, but it's been a while...
Anyway, once the back of the glove box is out, it is possible to remove the metal bracket behind the glove box. There are three torx headed self tapping bolts at the back of the glovebox that need to come out, then the two T27 torx bolts holding the bracket into the dashboard crossmember. Then there are the four small T15 screws holding the fan housing into the ducting. The bottom right one is very difficult to get to - but the torx screws have a 5.5mm hexagon head which makes it easier to remove. I had a set of ignition spanners which fitted. It might be possible to make it work with a 6mm at a pinch. Finally, with all those removed, it is possible to pull and twist the fan out of the ducting. It takes some time, and quite a bit of violence with regards to the back of the glovebox, but it can be done. I managed to pull the glovebox forward, get the bottom of the fan out, then pull it down. Once clear of the dasboard cross member, the top of the fan housing can be pulled towards you, and the whole thing will come clear.
Turned out one of the springs on the fan motor brushes had broken / disappeared. So no current to the armature, infinite resitance on the motor contacts measued that before I removed it).
Hope this helps someone before they decide to take the whole of the inside of the car apart. I'm goint to try and take pictures as I put it all together. That might also
help to show how it all works.
