Step 1 remove glove box, 6 screws on the hing, compress glove box slightly so inner track wheels are out of slots and remove.
Step 2 go to Google images and type blower motor for a 2003 or what ever year your Grand Prix is and you will find a good diagram of what you are looking for, as well you will see a picture of what the blower resister looks like.
Step 3 Now that you know what you are looking at remove the three small screws using a 6mm socket. Now the blower can be lowered and unplugged
Step 4 Look at the google image of the resister and locate directly behind the blower against the fire wall, unplug wiring leading into it. Time to remove the mounting screws, there are three screws but only two are visible. remove the two you can see and ease the resistor out the third screw hole is slotted so it does not need to be removed.
Step 5 install new resistor and plug all the wiring back in, reinstall blower and glove box. GOOD TO BLOW :)
Please note: The resistor screws are are a little tough to get to but if you use a 5.5 mm open ended wrench it is easiest.
Take it to a repair shop.
Resistor is located behind the blower motor assembly.
The blower motor speed resistor is burned out. You can replace only the resistor but the resistor probably burned out because the blower motor is going bad. If you want to fix it for good, replace both the blower motor and blower motor speed resistor.
Check to see if you are getting power to blower motor - if so replace blower motor If not check fuse, switch, resistor pack.
the resistor is gonna be right off the blower motor attached to the blower motor by a wire harness should be by the heater core
Check to see if you have 12 volts at the blower motor. If yes then the blower motor is bad. If no, then the resistor, relay, or fuse is bad.

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.
Replace the blower motor resistor block. It is located under the dash on the passenger side.
To replace a blower motor on the resistor first you take off the nozzle and then you go into the motor through the nozzle and unlock it then repeat and oil and done.
# Locate the blower resistor under the right-side of the instrument panel # Disconnect the electrical connector from the blower motor resistor # Remove the blower motor resistor mounting screws and remove the resistor from the housing # Installation is the reverse of removal
Blown fuse, bad blower motor switch, blower motor itself, or a defective blower motor resistor pack.
