SOURCE: heater bows cold when idling
You need to bleed the cooling system.
To do this park on level ground, when cold remove coolant filler cap, start engine and leave to idle.
Have plenty of warm/hot water available, when engine reaches operating temp it may appear to boil over so keep away from coolant filler, top up with warm/hot water and wait as it may bubble over a few times before settling.
Replace cap and hopefully back to normal, Remember your Anti Freeze?

SOURCE: Heat blowing cold air
Had the same problem on my car. The system was emptyed and vacuumed and them the right amount of pressure was added with the right amouht of liquid and the problem was fixed. My car wouldn't put out heat while sitting. But while moving, it would! But now it has been fixed.

same problem with my 2005 Altima V6, with only 44k miles on it!!! and this is the second winter in the last 4 years that I have to pay for a coolant flush to fix the problem. This time the thermostat is getting replaced too. Time for a new car!

Sounds like either your thermostat, which is the least expensive and easiest thing to change, or your water pump, or clogged radiator, which is a whole new world! The reason it wont blow hot, is because you are not getting any water to the heater core. Hope this helps.
