not really a lot to getting heat --- suggestions above will hopefully get you going. Its going to be either not enough hot coolant getting to/through the heater core (bad t-stat or clogged core or line), or the air going through the vents isn't going across the heater core due to a blend door issue, or as suggested, maybe even leaves!
