Mercedes A180 Cdi - Heater blower fan - no air in cabin - Cheeky

I have a 2006 A class with manual air con. Lately, for short periods of time, I cannot get any airflow in the cabin. It makes no difference whether the air conditioning compressor is on or off or the position of the air distribution dial.
The fan continues to work and I can hear the re circ flap changing position too, however, all air flow to the cabin is lost and only returns very gradually after setting the fan to its fastest setting and the vents to face level. Very slowly, airflow returns.
Is there a resistor for a sealing flap that could be jammed? Cabin filter is ok I think. Thanks for any assistance folks.

I would definitely check the cabin filter first.Any blockage here will seriously reduce air flow.There is no sealing flap on these.There is a fan speed resistor located in the heater housing on the right side of centre console,by drivers left leg,but usually when these fail,the first 3 speeds of fan control are lost.hth
