I will say one time I got a bus from Consett when it was like -1 after the bus had been parked up for like 3h and that was freezing as well and still the AC vents at the front were still blowing with all their might like usual, got I hate those things.
Bar a small handful of vehicle types (Optare Solo's spring to mind), I don't think drivers have any control over passenger saloon heating.
In terms of MMCs, I find it interesting that your experiences on them are constantly cold. I commute to work on a route that primarily uses E400 MMCs and, bar one or two, they're always warm - most days I need to take my coat off. They're never as obnoxiously warm as some older deckers, but I don't believe they're meant to be, I'm sure the heating is controlled by a thermostat so it'll turn off before it starts to boil everyone onboard.
Note on the vents at the front, unless the bus is fitted with an air conditioning unit, the air coming through won't be air conditioned.
