Blower Resistor: Inspection
WARNING: This page is about a different car, the 2006 Hyundai Tucson. However, it is still accessible from the selected car via links, so may be relevant.
Measure terminal-to-terminal resistance of the blower resistor.
If measured resistance is not within specification, the blower resistor must be replaced. (After removing the resistor)
