Detailed Product Description

The RU-835 blower motor resistor from Standard Ignition is engineered to control the fan speeds of the HVAC blower motor in Porsche 911 vehicles. It features a screw attachment method for a reliable and stable fit. The resistor supports multiple speed settings, ranging from 3 to 5 speeds, allowing for precise adjustment of airflow inside the cabin. This part comes without a wiring harness or mounting brackets, so it is intended for direct replacement where existing hardware and connectors are reused. The resistor terminals are male blade type, with two terminals to connect to the vehicle’s wiring system.

Compatible Vehicles and Applications

This blower motor resistor is compatible with Porsche 911 models, providing a direct fit replacement for the original equipment. It is designed to restore proper blower motor speed control when the existing resistor fails or malfunctions.

  • Resolves inconsistent blower motor speeds
  • Fixes blower motor stuck on one speed
  • Eliminates no airflow or limited airflow issues
  • Addresses HVAC blower motor resistor electrical failures

Installation Notes and Tips

Installation requires removal of the old blower motor resistor and securing the RU-835 unit using screws. Since no wiring harness or mounting brackets are included, reuse the existing hardware and connectors from the original part. Ensure the male blade terminals align correctly with the vehicle’s wiring connectors. Proper installation will restore full blower motor speed functionality.
