Blower Motor Resistor
WARNING: This page is about a different car, the 1997 Suzuki Esteem. However, it is still accessible from the selected car via links, so may be relevant.
Using an ohmmeter, check terminal-to-terminal resistance between all blower motor resistor terminals. Blower motor resistor is located behind glove box on blower motor case. If continuity does not exist between any 2 terminals, replace blower motor resistor.
