Heater valve failed shut. Vent baffles not opening, heater core blocked
There can be numerous faults such as (1) heater controls broken, cables bent, vacuum hose unplugged, (2) Thermostat closed, not working, (3) Fan motor burnt out,(4) Low anti-freeze coolant in rad, (5) wiring(short),hoses(kinked) (6) Thermostatic switches in rad, (7) Waterpump.
Its hard to tell unless one knows the year,make,model of vehicle as many vehicles can have either electric fans attached to rad or just the normal water pump driven by a belt.
