Check to make sure that hot water is making it to and from your heater core. There are usually two lines that direct water (coolant) to and from the firewall from the engine (not the A/C) system. These lines are usually heater hoses.
If both of the lines are hot, there's a problem with the blend door, or an electrical fault in the controls or wiring. If one line is hot and the other one cool, your heater core is either plugged or had an air pocket. The latter will require bleeding the cooling system and the former will require replacing the heater core, (not a job for the faint of heart). Also, check the thermostat to make sure it didn't fail in the open position.

Heater not blowing hot air in cabin


Check the coolant level. Check for leaks. Next would be clogged heater core(doubt that 2004) next would be the water pump. Kind of doubt that also, 2004. But if you have leaks?
