The first place to start is to feel the hoses going into the heater core.
They should be HOT when the car is fully warmed up.
If both are hot, then the heater core valve is probably stuck closed and not putting any water through the core. This is a common failure and not too bad to replace.
If the hoses only feel warm, then the thermostat is probably stuck open, which is not allowing the car to warm up fully.
The waterpump is connected by a belt and runs all of the time. The thermo wires are for the fans, and has nothing to do with the heat in the cabin. The fans make sure the car doesn't overheat.
