2013 ford edge heat only blows cold air
Heater only blowing cold air. Have already checked/tested thermostat and
heater control valve. Both seem to be operating normally. Have also flushed
heater core, with no obstructions. Have also tried (from inside car) the
power/defrost buttons to reset the heater, but this didn't work either. Looking for
other suggestions before I take to a mechanic for diagnosis.
Check the heater hoses, both should be hot. If they are, it's the mode-blend door. If they are not, water isn't getting through the core.
