Why does the 2017 ford f250 have no heat?

If Your 2017 Ford F-250 has no heat then there are a few things that could be wrong. The first thing that You should check is the blower motor. If You do not have any air pressure at all from the vents then that is a sign that the blower motor is not working properly. If You do have air pressure but just no heat then the next thing to check is the thermostat. This controls where the warm coolant goes, the coolant will either go back to the radiator or into the heater core. If the thermostat is okay then You will want to use a UV dye to test the heater core and see if there are any leaks in that which could prevent it from working.
