If all your getting is ambient air with no temperature changes (you'll notice when it gets hot obviously...) then the 2 temp blend motors are not moving to control the temperature.....The blowers do work - and they HEVAC blower control works too.
I just get varying degrees of power - all at ambient air temp.
The HEVAC buttons all appear to work, windscreen, feet, face etc all work as they should.
Can anyone reccomend a good garage in South East London / North Kent or beyond?
Get the codes read, and see what happens.
