Installation Notes and Tips

When installing the Dorman 973-113 blower motor resistor, ensure the vehicle is powered off and the battery is disconnected to prevent electrical shorts. Retain the original mounting hardware and wiring harness, as these are not included with the resistor. Verify connector orientation matches the rectangular female connectors on the resistor for proper fit. Tighten the two mounting bolts securely to avoid vibration or loosening during vehicle operation.
