Question 2001 Sunfire - No defog & no heater blower

I have a 2001 Sunfire 4 door 2.2L as of this morning I have nothing coming from the blower, when I turn the fan dial the defogger also is not working (rear is ok), No noise... I heard that this is quite a common thing and sunfires are known for this problem. I was also told that it could be a resister?
I purchased a Hanes manual and it does not show where this is located and I really dont want to take it to the dealer and pay $75hr (Cdn) shop fee just to tell me where it is. It only shows where the blower motor is......I checked the fuses on the inside panel and they are ok. Under the hood there is a fuse panel also on the right side above the winshield reservior it is a grey square (4 way) about 1 X 1" block type fuse.........should I replace this also? Sorry if I dont know all the correct mechanical terms lol......I am a female trying to find an answer to this problem. Thanks in advance.
Any help would be appreciated.

The blower motor resistor is right next to the blower motor. Turn the blower motor on with the ignition on, and tap on the motor. Usually they will free up and begin to work. If no good, unplug the blower motor and put a test light between the 2 terminals of the harness, not the blower motor, and see if it lights up. If it does light up, the blower motor is junk. Usually when the resistor fails, at least 1 speed will still work.

Thanks so much, it was indeed the resistor, all speeds are working now, not as big of a job as i anticipated, thanks again........
