Smith please help with it getting cold i can not afford to have my furnace go out with kids in the house
 
Blower has a metal shaft through the middle that turns the fins that blow the air. Oil ends of shaft. Any light oil will work if that`s all you have. If you are sure it`s blower and only makes noise when starting, it should work some time before it would stop completely.
 
You should really have someone take a look at it that knows what they are doing. Turn off the power to the unit before you go messing with the blower or you could lose a finger or hand. Some motors have something that looks like a 1/4 inch high piece of tubing with a flip up cap on it. You lift up the cap to put the oil in. Your local auto gas station should have sae 20.
