Detailed Description
The RU-851 is an HVAC blower motor resistor used to regulate blower fan speeds in the Subaru BRZ. It is a direct-fit electrical replacement for vehicles with the specified connector and terminal configuration, making it a practical choice when the cabin fan only works on certain speeds or stops responding correctly. This Standard Ignition RU-851 also cross-references 73532AJ010 for the same application.
Compatible With 2013-2014 Subaru BRZ and 2015-2020 Subaru BRZ, this resistor is listed for vehicles without automatic AC systems. If you are searching for a Subaru BRZ blower motor resistor, HVAC fan resistor, or RU-851 replacement, this part matches the documented fitment and electrical layout.
Common Issues This Part Can Address
- Blower fan works on only one or a few speed settings
- Cabin air fan does not respond at certain speeds
- Intermittent HVAC blower operation
- Loss of lower or medium fan speeds
- Failed blower resistor causing inconsistent airflow control
Installation Notes and Tips
Verify the connector shape, terminal count, and speed range before installation. This part mounts with screws and does not include a wiring harness, mounting bracket, or hardware. Confirm that the vehicle is not equipped with automatic AC systems before ordering, and compare the original resistor to RU-851 for connector and terminal match.
Quality Assurance
Standard Ignition supplies OE-style replacement electrical components for HVAC repair applications. RU-851 is built to match the documented Subaru BRZ fitment and connector requirements for a straightforward replacement process.
