I have 2002 Mitsubishi eclipse and my heater does not work so much. A little bit of warm air comes out from the passenger side vents and cool air comes from the drivers side vents. and when i turn it up to 2 to 4 it blows but its cool air.
Check your antifreeze level and if low then add antifreeze until the radiator is full and the overflow tank is up to the correct level. that should solve your problem. If it isn't that, chances are your thermostat could be stuck open which isn't allowing the coolant to warm up properly.
Good Luck
Then you have an air pocket in the engine somewhere. When cool, take off the radiator cap and start the car. Let it run and let the air pockets work their way out especially once the thermostat opens up. You will see the level go down after it has been running a while and keep adding until the radiator stays full. Then fill up you overflow tank up to the hot mark and you problem should be solved.
