There are many obvious things to check first before going really deep. Is the heater still connected? Maybe the core leaked and a previous owner disconnected the heater hoses. Is the heater valve stuck closed? If it leaked and corroded it might not function. Is the cooling system filled with anti-freeze and all of the air bled out? If the cooling system is low on coolant you won't get heat and if the core is full of air you still won't. Once you can get the core to heat up now see if the fan is blowing enough air over it to transfer the heat. Areas to check are fan rotation, mode switch for vacuum leaks and proper operation, vacuum motors for proper activation of the duct doors, etc. Maybe the motor doesn't have a thermostat so it never really gets warm enough to give you heat. A heater hose could be kinked. You get the idea. A good visual inspection usually turns up the culprit.
