Heater core flush

So now that the temp is cooling my heater vents arent changing like they should(like going from defrost to floor to vents)they do still change like they should it just takes awhile sometimes

So would flushing the core help with this problem or any suggestions ? Car has 235k and its never been flushed.( I know I don't really have an excuse foe that either )
