Installation Notes and Tips
Installation of the Standard Ignition RU-392 blower motor resistor requires removal of the old resistor from the HVAC housing, typically secured by screws. Ensure the vehicle’s ignition is off and the battery is disconnected before beginning work. The rectangular female connector should be carefully unplugged from the old resistor and connected to the new unit. Confirm that the four blade terminals align properly and that the resistor is mounted securely using screws (not included). No wiring harness or mounting brackets are supplied, so reuse existing hardware and wiring. Testing the blower motor speeds after installation is recommended to verify proper function.
