Question about 2002 Buick Century
I have a fan problem as the first two settings don't work. I believe the resisitor is going and I believe it is located behind the glove box. Please confirm the r &r on this .
I also have the master switch? on the driver's door that has intermittent problems. What is the name of the part and how do I remove and replace this?
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 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 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.
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.
I believe the driver door switch just pops out if you pry on it, but not absolutely sure on this one.
