I have a 2000 Grand Prix with the same problem. I found this response on another website:
"The problem is the blower motor resistor. This is a very common problem. It is located under the passenger side of the dash in front of the blower motor. The replacement part should be an updated and improved design."
Now I just have to figure out how hard to get at this is gonna be.
I had the exact problem w/ one of my own. It is the resistor board. It is common on GM vehicles newer. They redeigned this particular part due to failure history. It is simple to change;also. It is located on the righthand side of the vehicle inside the cabin. Look down in the corner near the firewall and you will see a cvr that needs to be removed. After removing that cvr you will see a harness with a plug on it. That's it. Remove the two screws and wala the resistor bank appears. Reverse these steps to complete. HAVE A GOOD TIME!!!
it is probley not the blower switch. if your fan runs on 3,4 and 5 it is your blower motor resister.
Bad fan switch Bad fuse Bad resistor pack on blower motor Bad blower motor
blower motor bad or no power to it chech fuses blower switch blower motor
Blown fuse, bad blower motor switch, blower motor itself, or a defective blower motor resistor pack.
The fact that you are having blower motor AND headlight problems points to ignition switch failure. Power to both systems comes from the ignition switch and this is a common Grand Prix problem. Here's the fix: http://www.clubgp.com/newforum/tm.asp?m=20670
it is on the firewall and difficult but not impossible to get to and replace.
If a 2000 Grand Am sometimes has the heater blower working and sometimes it won't, the problem could be with the heater relay switch. The heater relay switch lets the heater blower know when to come on and when to go off. In most vehicles this switch is behind the glove compartment. This part sometimes gets corroded from condensation in this area.
Typically a relay or resistor. But could be a blower switch or blower motor problem.
Bad Blower motor fuse Bad blower motor resistor Bad blower motor Bad switch Evaporator plugged- not allowing air flow
Bad blower motor fuse? Bad blower motor resistor pack? Bad blower motor - checck to see if it is getting power--if so bad motor Bad switch?
blower motor resister is bad
Blower switch and connection had a melt down.
Well it is apparent that all is not ok. The speed of the blower motor is controlled by the blower motor speed control switch and the blower motor resistor pack. One of those two items is your problem. I would bet the blower motor resistor pack is defective. The only way to know for sure is to replace it.
How to change blower motor on 2000 grand am gt
Bad fuse? Bad switch? Bad selector switch? Chck to see if motor is getting power and ground. If so probably a bad blower motor
Answeryou could just have burned out leads in the actual switch and that should be all you need to replace blower motor resistor.....its about $20 and takes about 30 min to replace...look it up on youtube
o4 grand prix gt blower motor were is it located
It's the ignition switch. Replace it. All will be well.
I mean how do you disassemble the fan blower in a 1998 Jeep Grand Cherokee Laredo. how do you remove the blower fan from the car in the Grand Jeep Cherokee Laredo.
grand am what? If it is a 99 Grand Am 2.4 like mine, we went throught the same thing. You have to take out the Glove Box. where is the blower mot or for a 95 grand am 3.1
Bad blower resistor? Bad switch?
Pull blower its up inside hole
behind dash is a small switch with a small hose hooked to it It may be a vacuum leak on the hose the problem can be the switch gone bad
The blower may simply have burned out. If the blower is out then the heater probably still works.
trying to locate ,the resister to the blower motor foe 2003 grand prix gt
