Keep heater and A/C airflow adjustable with the Standard Ignition Blower Motor Resistor RU955, a direct-fit replacement for the 2013-2022 Chevrolet Trax, 2012-2020 Chevrolet Sonic and 2012-2015 Chevrolet Spark. Specifically designed for GM applications, this HVAC blower motor resistor controls how much current reaches the blower motor, so the fan can run at more than one speed.
Signs this part may need replacing include a blower that works only on its highest setting, fan speeds that drop out, or no airflow at the lower settings. A switch, the wiring or the blower motor itself can cause similar symptoms, so diagnose the cause first. If a failed resistor is to blame, RU955 replaces it. See the Buyer's Guide tab for engine details.

This part cross-references / interchanges with the following part numbers:
Is this the right Chevy Trax blower motor resistor for a 2019 model?
Yes. RU955 is listed as a direct fit for the 2013-2022 Chevrolet Trax, which includes the 2019 model year.
Does it also work as a blower motor resistor for a 2012-2020 Chevy Sonic?
Yes. It is listed for the 2012-2020 Chevrolet Sonic, and it also fits the 2012-2015 Chevrolet Spark.
What does a blower motor resistor do?
It limits the current flowing to the blower motor at the lower fan settings. This lets the heater and A/C fan run at different speeds instead of only one.
What are the signs of a failing blower motor resistor?
The fan may run only on its highest setting, skip some speeds, or stop at the lower settings. A switch, the wiring or the motor can cause the same symptoms, so diagnose the cause before you replace any part.
Why does this resistor use copper connectors?
Standard Ignition uses premium copper electrical connectors to give more precise resistance values. It says this improves resistor performance and gives the part a longer life.
