Question about 2003 Buick Century
Heater/AC fan has four speed settings. It does not blow when set on either of the two lower settings.
Your fan uses resistors to reduce the speed of the fan. Hi speed doesnt use the resistors and that is why it runs on hi. Standing in front of the car, all of your heater housing is on the left side of the firewall You will see a connection with about 4 wires That look like they go nowhere. Take the couple screws out and pull it out. You will be able to see the burnt one.Jump out the burnt on and that will give you another speed or two.
