I did this job on a 1999 Grand Prix, and I believe the location is the same for the 98 year model. First of all you will have to remove the blower motor itself. It is located on the passenger side floor board below the glove compartment, up against the firewall. It is an awkard job and I found that what worked best for me was to lay on my back with my head up against the center console. Once you have removed the 4 screws that mount the blower, disconnect the electrical connection and remove the blower. It is a tight fit around a wiring harness that is in the same area, but with some effort, it will come out. The blower motor resistor is located inside the duct work where the blower motor goes. There are 3 screws holding it in place, one of which is hard to see. A mechanics mirror comes in handy to locate the hidden screw. I would also advise that you replace the blower motor along with the resistor so that you don't have to go through the aggrevation later. I bought both parts through the local Auto Zone, which was much cheaper than the dealers cost. Both worked just fine. Good luck.
Resistor is located behind the blower motor assembly.
trying to locate ,the resister to the blower motor foe 2003 grand prix gt
the resistor is directly behind the blower motor under the dash
Blown fuse, bad blower motor switch, blower motor itself, or a defective blower motor resistor pack.
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
o4 grand prix gt blower motor were is it located
Underneath the blower motor once you remove it it should be atachech with 3 screws near the upper lining
Bad fan switch Bad fuse Bad resistor pack on blower motor Bad blower motor
Buy a Chilton's repair book.
on the passenger side under the glove box
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.
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?
The blower motor resistor circuit board has gone bad. Replace the blower motor resistor. I did Still dont work Try the fuses...Had the same problem and it was a blown fuse.
The blower motor resistor is located right beside the blower motor which is on the right side of the instrument panel. You'll have to remove the lower insulator panel to see it. Remove the wiring connector and I believe there is 3 screws that hold the resistor in
easiest to pull blower motor then you can get at resistor, best to have a flexible extension (not a swivel) and you can access the bolts easier
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.
Defective blower motor resistor pack.
You need to change the blower motor resistor (under the passenger side glove-compartment). i have a 1997 Grand Prix with the same problem. A dealer can get it done but cheaper if you get the resistor from AutoZone, etc and have a mechanic or yourself change it.
Blower wont work on all 5 speeds, usually the lower speeds tend to go first.
It's on the passenger side of the car.Behind the glovebox,you will have to take the glovebox off the dash.then you will have to lay on the floor on your back,looking upward by the firewall you will see the blower motor.look behind the blower motor you will see a wire harness conected to the blower motor.Thats the resistor,after you un hook it from the blower motor you will have to take the blower motor out.It's held in by three screws,once you have taken the blower motor out,follow the wire harness that you've taken off the blower motor.you will then see the resistor with much effort its easy to get out,it's held in with two screws,you will only take one screw out to get the resistor out.
I had to replace a b.m resistor on my 05 Pont. Grand Prix and it was not that difficult and saved me a bunch of money. As fas as I can tell, and as in my case, if your blower motor is staying on high (even with the key out) then you have a bad resistor. The cost of mine for the 05 was $70. It was actually cheaper at the dealership and was in stock. It was really simple to replace. On the Grand Prix it was located under the glovebox. It's not very big and should have a wiring harness running into it and then from the resistor to the blower motor. There were two screws holding it in and just the one harness to re-attach. If you have anymore questions let me know. email@example.com
remove the cloth kick panel under the passenger side dash the blower motor can be seen once you do this remove screws and replace may be a good idea to consider the Blower Motor Resistor as well pn #89018643 if you have atc (auto temp control) blower motor pn #52489322 these are available from GM
the blower moter resistor is located on the passenger side. remove kick panel under dash and it is staight up against the firewall. three 5.5mm bolts hold it in,it is very tight in there.gm Jim
Usually against the passenger firewall
