Question about 2003 Buick Century
2003 Buick Century. The low speed blower does not work (the 2 lowest settings). I checked all of the fuses, all are ok. There are some lights out on the face plate for the blower/ac, and there are some lights out on the radio. Not all of them, just a few. Is the problem likely under there somewhere? And, what would I be looking for? And, how hard is it to remove and get in there, without screwing things up or making everything look bad when I put it all back together?
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.
