Standard Ignition RU1056 HVAC Blower Motor Resistor

Standard Ignition RU1056 HVAC Blower Motor Resistor

Standard Ignition RU1056 is an HVAC blower motor resistor for vehicles with 3-5 speed blower control. It is built with a plastic and metal housing, a bolt-on attachment method, and a female connector with male blade terminals for a direct electrical connection.

Compatible with 2018-2020 Buick Regal Sportback and 2018-2020 Buick Regal TourX, this blower motor resistor is a fitment-based replacement for restoring cabin fan speed control. The RU1056 is a practical choice when the blower only works on certain speeds or stops responding as expected.

Key Features

• HVAC blower motor resistor for 3-5 speed systems
• Bolt-on mounting for secure installation
• Female connector with polygon shape
• Male blade terminals, 2 + 2 terminal layout
• Black and silver finish with plastic and metal housing
• Fits 2018-2020 Buick Regal Sportback and 2018-2020 Buick Regal TourX

Detailed Description

The Standard Ignition RU1056 is an OE-style HVAC blower motor resistor used to regulate blower motor speed in the cabin heating and cooling system. It is specified for 3-5 speed applications and uses a bolt-on design with a female connector and male blade terminals for proper electrical interface. This part number, RU1056, is also cross-referenced for the same application with Monroe Shocks & Struts 172286 and 182286.

For Buick Regal Sportback and Buick Regal TourX models from 2018 through 2020, this resistor supports restoration of normal blower operation when the HVAC fan no longer changes speeds correctly. Standard Ignition RU1056 is a direct-fit replacement for the listed vehicles and should be matched to the original connector style and mounting layout before installation.

What It Is Used For

• Restoring blower fan speeds that only work intermittently
• Correcting loss of one or more HVAC fan speed settings
• Replacing a resistor that causes weak or inconsistent cabin airflow
• Addressing HVAC blower operation issues in 2018-2020 Buick Regal Sportback and Regal TourX
• Replacing a failed RU1056-style blower motor resistor

Installation Notes and Tips

Verify the connector shape, terminal count, and mounting style against the original part before installation. Inspect the blower motor and related wiring for heat damage or corrosion, since a damaged circuit can shorten the life of the replacement resistor. Confirm the vehicle uses a 3-5 speed blower control setup and follow the service procedure for the HVAC case location.

Quality Assurance

Standard Ignition replacement electrical components are built for service-fit accuracy and dependable HVAC system repair. RU1056 is listed for the confirmed Buick Regal Sportback and Buick Regal TourX applications shown above.
