Glad to know it's not just my imagination then
Currently I'm on Auto mode with fan set to 5 with the hope of getting more air in the foot well but no joy. The window defrosting is a bit loud and at the moment unnecessary since I've got heated windscreen so I might set the fan speed back to 3.
I have no complaints about the actual heating, I don't like it too hot and 21.5 degrees is spot on for me. I have steering and set heating set to come on automatically which helps a treat on those colder days.
It's a minor niggle but on colder days my feet gets a bit chilly compared to the rest of my body.
I might have a closer look at the footwell tomorrow to see if there are vents.
