Product Details and Specifications

The Dorman 984-278 blower motor resistor is built with a rectangular male connector housing one connector, which simplifies installation and ensures a secure fit. It has four female blade terminals designed to interface with the vehicle’s wiring harness, although the wiring harness itself is not included. The resistor mounts using two bolt holes, providing a stable and vibration-resistant installation. This part is essential for controlling the speed of the HVAC blower motor by regulating electrical current, allowing for multiple fan speed settings in your Saturn vehicle.

Common Applications and Problem Resolution

• Restores blower motor speed control in Saturn L100, L200, L300, LS, and LW series vehicles
• Resolves issues with blower motor only working on high speed
• Fixes intermittent or no airflow from HVAC vents
• Addresses blower motor resistor failure symptoms such as inconsistent fan speeds
• Improves overall HVAC system performance and comfort

Installation Notes and Tips

Installation requires removal of the old blower motor resistor and replacement with the Dorman 984-278 unit. Ensure the vehicle’s ignition is off and disconnect the battery before beginning. The resistor mounts with two bolts (not included), so retain the original hardware or source appropriate replacements. Connect the rectangular male connector securely to the vehicle’s wiring harness. Follow the included instructions carefully to avoid damage to the resistor or electrical system.
