Where is the blower motor resistor for a 2003 Avalanche?
The blower motor resistor for a 2003 Avalanche is located on the driver's side, behind the carpeting on the floorboard of the vehicle. It is attached to a bracket on the side of the blower housing. To access it, you must remove the carpet and detach the blower motor resistor from its bracket and unclip it from its plug.
