04 1.6 Heater Fan wont turn off (Auto air con) - smg
The blower control switch does not work and the heater/cooler fan runs constantly. I have read some of the previous posts on this topic but not sure that they relate to my model. My model has an Auto setting for Air con. Haynes don't seem to cover the facelifted model, so am struggling to find the Resistor pack/speed regulator on my model. Any diagrams/photos that anyone has would be helpful. When I remove the glovebox and passenger footwell carpet, all I see is the heating/cooling unit. Any help greatly appreciated

If its the same blower as used by the Xantia it has two regulator transistors mounted on the motor, these can go short circuit and cause your problem. Alternativly, the fault could be with the control panel, in which case removing the single plug with the thin lead from the motor should stop it, if not it will be the transistors.

On the Xantia it is acessed via the trim panel underneath the glovebox, two plugs and three screws, easy to remove.
