Keep your fan speeds responsive with the Standard Ignition HVAC Blower Motor Resistor RU1053, a direct-fit replacement for the 2017-2023 Chevrolet Bolt EV and 2022-2023 Chevrolet Bolt EUV. The blower motor resistor sets the voltage delivered to the blower motor at each speed setting, so the fan runs faster or slower as you turn the HVAC control — when the original resistor fails, the blower often works only on high or drops speeds entirely.
Precise resistance: premium copper electrical connectors deliver more accurate resistance values for consistent speed control and longer part life.
Variable-speed control: helps restore A/C and heater blower motor variable-speed operation, supporting proper HVAC performance and passenger comfort.
Seamless integration: the research and design process is aimed at clean integration with the vehicle's HVAC system.
GM-specific: designed specifically for GM applications and tested at the manufacturer's facility to confirm correct performance across conditions.
If a failed blower motor resistor is the cause of your lost fan speeds, this unit replaces it. Fits the 2017-2023 Chevrolet Bolt EV and 2022-2023 Chevrolet Bolt EUV — see the Buyer's Guide tab for full application details.
Interchange: RU1706 · BMRA271 · BR999 · 84496889
This part cross-references / interchanges with the following part numbers:
What does this blower motor resistor do?
It regulates the voltage sent to the blower motor for each fan setting, allowing variable HVAC fan speeds. When it fails, the blower may run only on high or lose several speeds.
Will the RU1053 fit my vehicle?
It's a direct-fit replacement for the 2017-2023 Chevrolet Bolt EV and 2022-2023 Chevrolet Bolt EUV. Check the Buyer's Guide tab to confirm it matches your vehicle.
What numbers does this resistor interchange with?
It cross-references RU1706, BMRA271, BR999, and 84496889.
What are signs this part may need replacing?
Signs include a blower that works only on certain speeds or only on high, or a fan that stops responding to speed changes. Diagnose the cause before replacing.
What are the electrical connectors made of?
The resistor uses premium copper electrical connectors, which the manufacturer notes provide more precise resistance values for consistent performance and longer part life.
