- Package contents include a blower motor resistor, wire harness, and butt connectors
Detailed Description
This Dorman blower motor resistor kit is built for 2002-2006 Nissan Altima models equipped with manual air conditioning controls. It addresses common HVAC electrical failures caused by heat damage, corrosion, or connector wear at the resistor circuit. Part number 973-118 is a practical replacement when blower speeds stop working correctly or the original connector shows signs of overheating. This part cross-references OE-style applications such as 3A1313 and RU366 for the same repair need.
Common Issues It Can Solve
- Blower motor only works on certain fan speeds
- No airflow from the HVAC vents at selected settings
- Heat-damaged or corroded blower resistor connector
- Intermittent HVAC fan operation caused by electrical resistance at the connector
- Failed resistor circuit in manual climate control systems
Installation Notes and Tips
Verify that the vehicle has manual air conditioning controls before ordering. Inspect the blower motor connector and surrounding wiring for heat damage before installation, and replace any compromised terminals as needed. Confirm the mounting points and connector style match the original HVAC resistor location. For 2002-2006 Nissan Altima blower motor resistor replacement, compare the original part and harness layout to Dorman 973-118 before installation.
Quality Assurance
Dorman supplies replacement automotive electrical components engineered to address common OE failure points. This HVAC blower motor resistor kit is intended to restore proper blower speed control when the original resistor and connector assembly have deteriorated.
