Standard Ignition HS-543 HVAC blower control switch for the 2011-2013 Toyota Corolla and other vehicles controls the blower motor for the heater and A/C.
A fan that runs on only some settings, or not at all, can mean the switch is worn. Before you replace the switch, rule out a blown fuse, a failed blower motor or damaged wiring first.
It fits the 2011-2013 Toyota Corolla and the 2011-2013 Toyota Matrix as a direct-fit OE replacement.
