Can a bad radiator cap cause no heat?

Radiator cap: Your radiator cap regulates the pressure in the cooling system, acting as an escape valve if the pressure gets too high. If it sticks in the open position, there will be insufficient pressure in the system, and the coolant will not get hot enough, reducing the heater’s output.
