Blower Motor Switch Resistor
WARNING: This page is about a different car, the 2003 Mazda Tribute. However, it is still accessible from the selected car via links, so may be relevant.
The four-speed operation of the blower motor is achieved through the blower motor switch resistor and contains a thermal limiter which is used as a temperature protecting fuse. The assembly is located on the passenger-side on the evaporator core housing behind the glove compartment.
