Punto Evo Car heater

Sorry if I posted this in the wrong section but I’m new to this
My car heater has stopped working, after a cold morning around -3, the engine turned on fine and everything was normal except the heater. No heat would come out and the fan didn’t work, does anyone know what the fault might be???? I’ve been to a garage but they said I need to go to a auto electrician, I’m looking for one but was hoping to find a quick fix or something as with the weather being cold it’s a pain having to drive in the cold. Any help would be a appreciated

What heating system do you have is it turn dial to red for hot air and turn knob to 4 for more air, or is it a digital climate control system.

Different systems can have very different faults.
