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 blower motor is located under the dashboard behind the glove box. Remove the glove box, passenger side scat and the blower motor will be visable.
it is probley not the blower switch. if your fan runs on 3,4 and 5 it is your blower motor resister.
i broke down and paid to have this fixed. My mechanic said this is a fairly common problem on the older grand prixs. He had to replace the relay as well as the blower motor, total cost was $400.
