1. Make sure coolant is full (if opening the cap - don't do it on a hot engine or you get scalded)
2. Check the heater valve on the hose under the hood next to firewall - it should be moving freely with the adjustment lever. It's possible that the cable has slipped - disconnect it and open the valve by hand, see if that makes a difference.
3. Make sure the engine is hot - you shouldn't be able to hold you hand. If not - replace the thermostat.
4. If all of these check out OK, you may have air pocket in the heater core which is unlikely
5. Blown head gasket may cause this as well but based on age and likely high mileage - probably 200,000 + - it's a possibility.

I would first check the coolant level and rating to make sure it is doing its job. Then I would have the system is actually circulating properly, by having a pressure check done on your cooling system. In the event that your heater core is plugged, you might have this kind of trouble. Also, low coolant, a stuck thermostat, or even not running the car very long can all be reasons for not getting much heat in your car.
Good luck.

There is a valve on the fire wall that is cable actuated that allows hot water to flow through the heater core.Have this checked it could be the valve,the cable or the control,possibly a combination.

first check your antifreeze to see if it's low, get your cooling system drained and filled. also have your thermostat checked or replaced. good luck!
