Beck/Arnley HVAC Blower Motor Resistor P/N:204-0021
Regain control over your cabin fan speeds with the Beck/Arnley HVAC Blower Motor Resistor 204-0145, a direct-fit replacement for the 2010-2013 Mazda 3 (see the Buyer's Guide tab for engine-level fitment). The resistor sits in the HVAC circuit and varies the current sent to the blower motor, setting the lower and mid-range fan speeds you select on the climate controls. When a resistor fails, the blower commonly runs only on high, or certain speed settings drop out entirely — if a faulty resistor is the cause, this part replaces it.
Diagnose the cause of your fan-speed issue before replacing, as wiring, the switch, or the blower motor itself can produce similar symptoms.

This part cross-references / interchanges with the following part numbers:
What does this blower motor resistor do?
It varies the current supplied to the HVAC blower motor, which sets the lower and mid-range cabin fan speeds you choose on the climate controls.
What vehicles does the 204-0145 fit?
It is a direct-fit replacement for the 2010-2013 Mazda 3. Check the Buyer's Guide tab to confirm the application for your specific vehicle.
My fan only works on high — will this fix it?
A failed resistor often leaves the blower running only on high or loses certain speeds. If the resistor is the cause, this replaces it; verify wiring, the switch, and the motor first.
Is this a genuine OE part?
It is a Beck/Arnley OE-quality replacement engineered to match the original's form, fit and function for this foreign-nameplate application.
What numbers does this part interchange with?
It cross-references 2400635296, RU1595, BBM461B15, RU906, WP332560OES, and 4P1711.
