Really? That's weird since the heater fan was fully off until 4:18. It's true that me heater fan makes weird noises. The garbling sound it sometimes makes (not featured in video) tends to worry passengers.

Question: you say you have cardboard over the radiator. Do you mean over the grille, or the radiator? You'd have a little more heat retained if you blocked the grille itself.

Yeah, the cardboard is slotted directly in front of the radiator itself. Sometimes the car's temperature will nearly overheat with it on during highway speeds (I slide it over a bit to have some air going through, to prevent overheating) and the complete opposite while city driving.
