Beck/Arnley HVAC Blower Motor Resistor P/N:204-0021
Take command of your cabin fan speeds again with the Beck/Arnley HVAC Blower Motor Resistor 204-0133. This resistor sits in the blower motor circuit and steps down voltage to set the lower and mid fan speeds, so your climate system can move air at more than just the highest setting. It's built as a direct-fit replacement for the 2003-2008 Mazda 6 — see the Buyer's Guide tab for engine-level details.
If a failed resistor is the cause of a blower that only runs on high, drops certain fan speeds, or stops blowing entirely on some settings, this replaces it. Diagnose the cause before replacing, as switches and wiring can produce similar symptoms.
