Dorman - OE Solutions HVAC Blower Motor Resistor Kit P/N:973-578
When an overheated or corroded resistor is the reason your cabin fan won't change speeds, the Dorman blower motor resistor and harness pigtail kit, part number 973-118, is designed to replace it. It is a direct-fit replacement for the 2002-2006 Nissan Altima and supplies a new resistor together with a new connector.
A blower motor resistor helps regulate how fast the HVAC blower motor runs at each fan-speed setting. Because heat and corrosion can damage the wiring connector as well as the resistor, this Dorman hvac blower motor resistor kit includes a harness pigtail, so both can be replaced in the same repair.
Signs this part may need replacing include a blower that runs on only some speed settings, no blower operation, or a melted or corroded resistor connector. Diagnose the cause before replacing parts. See the Buyer's Guide tab for complete application details.

This part cross-references / interchanges with the following part numbers:
What does a blower motor resistor do?
It helps regulate the blower motor's speed at the different fan settings, so the HVAC system can move air at lower speeds as well as higher ones.
What comes in the Dorman blower motor resistor kit?
Each 973-118 kit includes a blower motor resistor and a harness pigtail, so a damaged connector can be replaced along with the resistor.
Does this resistor kit fit the 2002-2006 Nissan Altima?
Yes. It is a direct-fit replacement for the 2002-2006 Nissan Altima. See the Buyer's Guide tab for complete application details.
What are signs of a failing blower motor resistor?
Common signs include a blower that works only on certain speeds, no fan operation, or a melted or corroded connector. Diagnose the cause before replacing parts.
How is the resistor and pigtail kit installed?
Disconnect the battery first. Then follow the vehicle service information to reach the resistor and to connect the included harness pigtail.
