windscreen heater not working

hey everyone,
when the heater is blowing onto the windscreen, there is no air coming out of the vents running along the dash, the other functions like feet and face vents are fine. ive had a look at similar posts, and tried changing from hot and cold, on cold there is air coming onto the screen through the vents, but when changed to hot the airflow is reduced massively to hardly anything. does these mean the matrix is blocked with 13 years of crud?
thanks

The big flow difference between hot n cold sounds like a blocked heater matrix.

A blocked pollen filter on some models would restrict overall flow even when set to cold full blast.

Flow not being diverted to the windscreen correctly could be a misaligned/slipped outer control cable

Is your pre facelif or facelift Micra?
