Low heat temperature in a 2003 Ford Focus can be caused by several issues, including a low coolant level due to leaks or evaporation, a malfunctioning thermostat that may be stuck open, or a failing heater core that is not circulating hot coolant properly. Additionally, a clogged radiator or a problem with the water pump can also hinder effective heating. It's important to check these components to diagnose the issue accurately.
