Cars used to have water valves for the heater circuit. I'm guessing that all now have a permanently hot heater matrix and just blend hot and cold air.
It should be fairly easy to tell whether the coolant is getting hot, which it will be if the thermostat has been replaced. If the car's still cold with the controls set for heat and the fan's going, then the flaps aren't in the right place. I had a Scorpio with this problem and a reset of the CC system fixed it a couple of times, there was a button pressing routine to do it.

There might be something similar for the Squashy, it might need plugging in to the diagnostic system to do it, but you'd expect a dealer to do that.
If it's not the control system then a physical jamming of the flap or a motor problem could be to blame. With CC you have a few more bits going on as well with inside and outside temp sensors, air output temp sensors sun sensors etc. If one of those fails it might take somebody with a brain and a bit of patience who can properly interpret fault codes to fix it.
