I have an '02 fabia SDI estate, all good except for the heater controls have a mind of their own. The problem is with the control to set the temperature only, everything else seems fine, sometimes you turn it up and nothing happens, later in the day it will then blast heat out and when you then turn it to cold it keeps blowing hot. Any ideas?

Bump!

Sounds like a problem with the heater flap motor, more information here:
