1990 Ford Probe Question: heater not blowing hot air

The heater blows out cold air instead of hot air. I've changed the thermostat. My car also overheats. What could it be? -
Answer 1
You may have a bad water pump, but get this looked at by a mechanic that can diagnose this and determine if any damage has been done to the engine from the overheating. -
