I suppose it would be a common fault if you fit a new unit and it fixes the problem,because you are doing the same as a battery disconnect reset.hth
Hello after reading the previous posts, I have a similar problem with my 2001 galaxy 2.3
heater controls.....The fan is working but seems to be stuck on cold also as with previous post I have no lights on the air con buttons and also it only blows onto the windscreen.
I have tried the battery disconnect / reset and tried removing and reinstalling the control unit
to no avail. Is my control unit dead....?
