I've had cars like that.
I recall that it's more likely where the car has climate control rather than air con.
In my case, it wasn't broken it was just the way that it works in auto mode.
It's the basic MB system - in auto it's absolutely hopeless, doesn't cool the car unless temp is clicked down to its lowest setting and then the fan goes to max speed. So I use it in manual all the time.
I should have pushed it more when it was newer (it's an ex-MB management car and I've had it since it was 5mths old). I wonder if the controller is faulty - indie shrugged and said there are no fault codes.
