Heater fan/blower

Post by elmerfud »

I bought a C3 this weekend ( second hand ) but since tuesday the fan is constantly on, no matter what I try it will not go off? I have spoken to the garage where I got it from, and they said it could be a sensor within the climate control, has anybody had this problem before and how did they fix it?

Is it on at full speed? Is it like as if the heater is in demister mode?
If so then the heater blower control module (power transistors in it) is malfunctioning and it has to be replaced.

Search in ebay to see pictures and the price of the component. The module seems to be same as in C5.
Search words would be like: "C3 Heater Blower Control Module Resistor"
