Citroen C3 Heater Blower constantly on full power even if switch is off!

2004 Citroen C3 Problem

The Problem:

My heater blower is constantly ON at FULL power even though controller switch isn't on!

Fuse is fine, had to unplug unit to stop.

Is this something can fix at home or do I have to book into a garage?

dont know for sure, but it is most likely to be in or around the heater matrix or blower motor fan box under the dashbord. hope this helps!!!
