check your thermostat, if that isn't it you might need a new heater core. had one put in my f150 for about $150.
With my car, it was Heater matrix clogged with radiator sealant. The workshop cleaned it and it's start working fine!

After changing the thermostat on a 1996 subaru legacy 2.2L my car is still overheating and the heater blows out cold air. what causes these problems?
When I answered this before I didn't know about the heater blowing cold air. All of that stuff I put in the other answer still applies but First I would check to make sure the radiator actually has enough anti freeze in it. One other thing that can cause a car to overheat is the water pump but I don't think that is your trouble. Good luck.
