Well, this seems really odd, but last night while waiting at the fast food line, my heater started to blow cool air, or the same temp as what was already in the cool car anyway. Throughout the night I discovered (no pun intended) that it blew hot as fire (like normal) when driving, but when I let the engine idle it starts to blow cool air.

I don't know everything about heaters, but from what I do know this makes no sence what so ever. I have checked all the buttons and dials, and they are where they always have been for normal heater opperation and I have jiggled everything, so I can't figure this one out.

Check your coolant level... chances are it's low and there's air in your system. This will make it blow warm only when your car is moving. It probably takes a while to warm up too. Let me know if this works.
