Replace the blower motor speed control resistor 1st then the blower motor if the resistor doesn't fix the problem. Below are instructions to replace the resistor.

The blower motor resistor is located on the back of the blower motor housing under the dash on the passenger side. It can be difficult to get at, but it is doable. Be ready with the ibuprofen the next day for your sore back. Remove the cover panel from beneath the dash on the passenger side. Unplug the power 'ribbon' wires leading to the resitor. Unplug the wires that lead from the resitor to the blower motor housing. There are usually two, one black and one purple that share the same plug. Remove the short hose that leads from the blower motor housing to the ventilation system ducts. Remove the blower motor by removing the three hex screws that hold it in place. Remove the resistor by removing the three hex screws that hold it in place. The resistor is right against the firewall so two of the screws are very difficult to reach. A slender flexible socket extension will make the job easier. Attach the new resistor in place using the same hex screws. Only 1 or 2 of the original three are needed (the part is very light) if you do not feel like fighting with the ones next to the firewall. Reatach the blower motor and reconnect the hose. Plug the power cable wires back into the resitor and the wire from the resistor back into the blower motor.

Do you mean the blower does not work ? It is not blowing air ? If this is the case. Check waht is called a Resistor under the dash. It is located usually near the blower motor or on it. It has a plug and a couple of screws. replace the resis tor and see if it works. if not the blower may be bad.

    it is probably the Resistor . but as we both suggest if not the blower motor is bad.

Heater fan speed control only works on 3,4 & 5 on 2002 buick century .\r\n1 & 2 won't work. Is this a fuse problem????


No, it is not a fuse problem. Most likely you need to replace the heater blower resistor. A replacement should be available at your local parts store, and they should be able to help you find it's location. If you follow the wires from your blower motor, they will lead to this component. Usually two 7mm screws hold it in the heater box, but might be 5.5mm (7/32").
