Cold air not coming through vent

[slofizz]

I know the AC is working, but to get the cold air to flow into cabin i have to fiddle around with knobs until it works. Does anyone know how to fix this?

Try playing with the valve for heater core. It's just under the cowl in the middle of the engine bay.
