Heater and tire problems? 2003 Pontiac Bonneville?

All winter my heater has been going in and out. It's gotten really bad lately though.. because I used to be able to hit the dash and it would turn on right away again.. when it did turn on though there was a really loud rumbling noise but the noise went away after a while. Now, it blows hardly at all even if I hit the dash. Is this a fuse problem or a blower motor problem? Also, last night my tire pressure light came on. Does this mean that I have a leak in my tire somewhere, or is it normal for air pressure in tire to go down every so often? I looked at my tires and none seem to be flat, I just cant check the pressure on them until tomorrow so I was wondering if it was normal for the air to go down a bit every now and then.. or if you think I might have ran over a nail? I dont know.. i'm clueless on cars so any help would be greatly appreciated!
