How do I fix a heating issue in my Ford Mondeo?

My Ford Mondeo seems to be blowing cold air when I turn on the heat. How can I address this issue?

It's possible that your car's thermostat is stuck open, not allowing the engine to reach the proper temperature. This can cause the heat to blow cold. I suggest taking your car to a mechanic to have the thermostat checked and potentially replaced.

Another potential cause of this issue could be a clogged heater core. Over time, debris and sediment can build up in the heater core, preventing hot air from properly circulating. Have a mechanic flush out the heater core and see if that resolves the issue.
