Also this problem is related to a much harder problem to diagnose and fix.
If you use Air conditioning AC is on and randomly the car start blowing hot air then cold air by itself.
Or you use the heater and the heater power is lower than before this is because of the flap mixing air from AC and air from the heater core.
The Heater core uses the engine coolant and a radiator to bring heat inside the car cabin so heating will only work when the engine is warm not cold.
If the Heater does not work it might be the heater core being clogged - let me know if you want to see a video about how to unclog the heating core.

If the car moves from cold to hot by itself, this will fix it!
It works for both the air recirculation flap problems and for random changes from cooling to heating inside the car.
Watch the whole video without skipping. Watch the video BEFORE you start working on the car.
