Wondering if anyone could tell me what the correct part name for the  fan speed electronic controller for C4 1990.  (that's what we call it in Australia )

The part I am after is not the blower motor resistor but the electronic type which when used with the blower fan turns it on and off. at the moment the blower fan runs all the time. I had been advised the part I need is the electronic type but don't have the correct part name or number.

If anybody could help me that please.

Hello Tony

My 91 is doing the same thing. The part is called the Blower Control Module. They are readily available, cost seems to vary per supplier. I also read somewhere that if you can cross reference to another vehicle you might get it for less.

Good Luck
