Detailed Description
Dorman 973-115 is an HVAC blower motor resistor designed for 1999-2002 Nissan Quest rear systems. If the rear blower only works on certain speeds or stops responding altogether, this replacement resistor restores the fan-speed control needed for consistent heating and cooling. The part number 973-115 is built to follow the original equipment layout, using a single rectangular female connector, male blade terminals, and a 4-bolt mounting pattern for a straightforward service replacement. This Dorman blower motor resistor is also referenced by common aftermarket numbers used for the same application, including Four Seasons 20243.
Common Issues It Can Help Solve
- Rear blower fan works on only one speed
- Rear HVAC fan speed settings do not respond correctly
- Rear cabin airflow is intermittent
- Rear heating or cooling output is reduced because the blower circuit is not regulating speed properly
- Blower motor resistor failure caused by heat damage or electrical wear
Installation Notes and Tips
Verify connector style, terminal count, and mounting points before installation. This resistor uses 4 bolt holes, 4 blade terminals, and no wiring harness, so the existing vehicle connector and wiring must match the original configuration. Confirm rear fitment for 1999-2002 Nissan Quest before replacing the part number 973-115.
Quality Assurance
Dorman supplies this resistor as a direct replacement component for select OE applications, with instructions included for service reference. It is intended to restore the original blower control function on covered Nissan Quest rear HVAC systems.
