Blower Motor Resistor Inspection
WARNING: This page is about a different car, the 2011 Suzuki SX4. However, it is still accessible from the selected car via links, so may be relevant.
Reference: BLOWER MOTOR RESISTOR REMOVAL AND INSTALLATION
Measure each terminal-to-terminal resistance. If measured resistance is out of specification, replace blower motor resistor.
