Get every fan speed working again with the Four Seasons HVAC Blower Motor Resistor 20659 — a direct-fit replacement for the 2010-2013 Mazda 3 and 2010-2013 Mazda 3 Sport. This blower motor resistor controls the current sent to the heater/AC blower motor, setting the lower and mid fan speeds; when it fails, the blower often runs only on high (or drops certain speeds), and this replaces the failed unit if it is the cause.
Quality contacts: ensure proper conductivity for consistent fan-speed operation.
Vehicle-specific application: made for the listed Mazda applications rather than a universal fit.
OE-style connectors: match the factory harness plug for a straightforward swap.
Backed by Four Seasons' decades of mobile A/C experience, this Mazda 3 blower motor resistor is engineered and tested for reliable operation. Always diagnose the cause of a blower-speed fault before replacing, as wiring, the switch, or the blower motor itself can produce similar symptoms.
