Cant say for sure with the 2000 model but I assume its the standard blower resistor as my 1997 that failed twice. Symptom is the fan only works on high speed but not on thelower speeds or some of them. You can remove the resistor block (you need to be a contortiounist) not one of my fav jobs -lay on your back and its up on the firewall on passenger side, careful with the plug it has a retaining clip on the side- then meter it out with a ohm meter, refer to the diagrams in the car manual (service manual you can buy at parts centers).You can often buy a replacement on the Internet rather than paying the huge price at dealers..The second time my fan failed was due to no power to the connector intermittantly - I ran a new 12V circuit to the plug and its been like that for 2 years.. Good luck

Resistor is located behind the blower motor assembly.

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 resistor is to the left of the blower, it is very hard to get to. You'll have to almost stand on your head to change it.

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

maybe blown fuse or the connection in the blower resistor is damaged or the blowre resistor module is burn out the blower resistor is located in front passinger under the dach boared

The blower motor is failing and drawing too many amps.

Blown fuse, bad blower motor switch, blower motor itself, or a defective blower motor resistor pack.

If the blower only works on high the blower resistor is most likely the problem and should be replaced. On rare occasions if the car has blown the resistor more than once the blower motor shouuld be replaced.

The blower motor resistor that sits behind the blower motor itself all the way against the firewall.

It is located under the dash on the passenger side. The blower is located on the right side and has a two wire connector, the resistor is to the left of the blower. It is held by two screws, and has a four pin connector. Disconnect the connector, unscrew the two screws, and the resistor drops out.

it is under the clove box behind the blower motor you will see it if you look its a black box

Test the resistor bank before getting into anything else. These are the speeed controls for the blower motor.

i have an 03 grand prix and yes it was the blower motor resistor also check there is a fuse for fan low and fan high or something like that

The resister is right behind the glove box.

It does not have a ballast resistor, those were used for ignition systems 30+ years ago. It does have a blower motor resistor that is located behind the glove box.It does not have a ballast resistor, those were used for ignition systems 30+ years ago.
