2000 Buick Century. Blower quit working for

SOURCE: Front AC Blower quit working. Rear AC blower

The first thing I would do is check to see if a fuse is blown or bad relay. Then I would unplug the blower motor with a test light make sure you are getting power to the blower located on the far passenger side of the vehicle under the dash if it has power and good ground then suspect vaulty motor. If you are not getting power at the plug then you might have a bad switch or resister. If it does have a blown fuse remember they usually blow for a reason like faulty wiring or even a in the motor itself. I would also recommend that you change the ac cabin filters behind the glove box if they have not been changed most people neglect them on that vehicle because they are a little more difficult to change, after removing the glove box there is a metal bracket in the way of opening the cabin filter compartment. They wont cause a blower motor to not work, however they do restrict airflow to the evaporator and they protect you from pollen, dust, and even exhaust gases. Hope this helps.

The recharge of your a/c system and this is unrelated, could be a bad blower motor or blower motor resistor, have you checked your blower motor fuse? If fuse good, check voltage at blower motor, sit under dash on passenger side, just below dash, you will be able to see it, will have two wire's going to it, only one will have voltage with switch on, if you have voltage replace it, not that hard of a job to do, shop repair time to remove and replace blower motor is .7 tenths of an hour, hope this was very helpful.

You may have a bad blower motor resistor. The blower motor is located in the passenger side foot well. You will need to remove the kick panel on the passenger side to get at the motor. 
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. Remove the cover panel from beneath the dash on the passenger side. Unplug the power 'ribbon' wires leading to the resistor. Unplug the wires that lead from the resistor 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 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.Reattach the blower motor and reconnect the hose. Plug the power cable wires back into the resistor and the wire from the resistor back into the blower motor.


Good luck and hope this helps.

ASE mechanic:
blower motor regulators go bad because of the switching between low and high speeds. some times these are under the dash and require tiny hands and lots of patience.
