More than likely your Blower Module is shot, besides the obvious steps (fuse, power etc) you should have that checked. The fan clutch is another notorious culprit in GM cars. Good Luck!
Resistor is located behind the blower motor assembly.

Check your fuse box for a blown fuse and also check your connections at the blower motor.

Please email me a photo of where the blower motor resistor is and how to change it. Thanks, Michael. By the way I want it for a 2000 Sunfire not a Grand Am.

The blower rheostat on a 93 Pontiac Grand Am is located inside the engine bay, just to the right of the blower fan housing. It is almost directly behind the trans dipstick. It isn't that hard to replace.
The heater blower motor itself is located under the hood on the passenger side of the car.
