Blower not working

I recently discovered that when I tried to turn the fan to heat the car up nothing happened. One day it worked the next day nothing. I checked the blower fuse, and it was ok. I think the heater is working because I can feel some heat coming through the vents when I am driving, but nothing when I am stopped. Can anyone help me?

try moving the switch to the 4 position.

Also, search here. I know I've read about this a couple of time here.

There's a good chance that the blower motor itself is worn out. Sometimes they can get to a point where they work sometimes and sometimes not.

It doesn't matter what number I put it on, it doesn't blow. Where is the blower? How do it get to it? Any website that shows how to replace a blower. Could it be anything else? Is there a relay or any other type fuse I should check first?
