Not knowing what vehicle you have and the coolant reservoir is full, you may have a plugged up heater core or a temp blend door at fault. Run the engine and get it up to operating temperature (195 degrees F). Leave the engine running and open the hood. Feel both heater hoses with your hands. If one is hot and the other is noticeably cooler you probably have a plugged up heater core in which case you can try to flush it out. If both hoses are hot you may have a temp blend door that is not functioning in which case replacement or repair of the temp blend door switch or actuator would be necessary.
