check your fuse, check the wiring to the blower or the blower motor itself could be shot.
You can find a wiring diagram for a blower motor resistor in the owner's manual. You can also check with local supply stores.
Check your fuse box for a blown fuse and also check your connections at the blower motor.
Blown fuse, defective blower motor, blower motor resistor pack, or loose wiring.
Your wiring is probably messed up, happened to me. Locate the wires from the blower to the controls check them and replace as needed. Assuming no wiring problem check and replace the blower motor resistor.

Check for a bad blower resistor at blower motor
Fuse, blower motor resistor pack, blower motor, and blower motor switch, in that order. Failure of the blower motor connector on this model is common. Check www.wjjeeps.com for pictures and an explanation of the problem. Sometimes you can get temporary operation by jiggling the wiring connector. You also need to check for the source of the problem. It is also common for the re-circ door to break, blocking air into the fan and causing it to overheat, stressing the wiring. Check the HeaterTreater re-circ listing for diagnostic information and pictures.

How to change blower motor on 2000 grand am gt
Start by checking the fuse. If the fuse is good, apply 12 volts directly to the blower motor. If the motor runs it is good. Check all the wiring for loose or burnt wires. If all this checks out, then the Blower Motor Resistor Pack may be defective, or the blower motor speed switch itself.Start by checking the fuse.

Your inside blower motor is most likely bad and if not then check the capacitors and the wiring, but I would go with the blower.....
