There should be a little window on the front of the furnace through which you can see an LED. It will blink a specific number of times, and you look up the "blink code" in the book.

Educated guess is you have a FUBAR'd flame sensor.

I assume when you say "blower" you mean the inducer fan and when you say "fan" you mean the blower fan?

As alphapointe posted, check the LED error code.

Alternatively, call an HVAC tech (recommended).

If you aren't seeing any flame at all then it is probably a bad ignitor. If the flame sensor was bad then you would see the flame come on for a few seconds and then go back off.

If you know very little about furnaces, you shouldnt be attempting to fix it.... you could easily end up with a broken furnace that needs expensive parts to fix it... pony up a few bucks and call an HVAC man..
