If your 1998 Expedition is not blowing hot air, it could be due to several issues. Common causes include low coolant levels, a malfunctioning thermostat, or a faulty heater core. Additionally, check the HVAC controls for proper operation, as electronic issues can also prevent hot air from circulating. A thorough inspection of these components is recommended to identify the exact problem.
