Maybe if this system has an evaporator temperature sensor fitted it,s been knocked off or disconnected that would give that kind of symptom you describe.I would first look at this through scrolling values to see if it,s functioning and compare it with the cabin temp. Sensor value.other than that it,s also possible you could have a blockage if the pressure is excess. High,other thought is a faulty fan module ,but this would normally log a fault code.
