Detailed Description

This HVAC blower motor resistor connector is built for repairing damaged blower resistor wiring at the connector end rather than replacing the entire harness. Standard Ignition S2457 uses a female, rectangular connector body with male blade terminals, a 2-wire layout, and a push-on attachment style for a straightforward electrical service connection. The included wiring harness and splice connectors support a clean repair on 12-volt HVAC circuits where the original plug has overheated, melted, or lost terminal tension.

Fitment coverage includes 1990-1997 Mazda Miata, 1992-1996 Mazda MX-3, 1990-1995 Mazda 323, 1990-1994 Mazda Protege, 1990-1991 Mazda RX-7, 1985-1988 Mitsubishi Mirage, 1993-1995 Toyota 4Runner, 1989-1992 Toyota 4Runner rear auxiliary heater, 1981-1990 Toyota Land Cruiser rear, and 1996-1997 Lexus LX450 rear. This part cross-references EC2358 and PT2442 for the same application.

Common Repair Uses

Restores blower motor resistor electrical connection after heat damage
Replaces brittle or cracked HVAC connector housings
Fixes intermittent blower speed operation caused by poor terminal contact
Addresses melted or discolored resistor plugs in older Mazda, Toyota, Lexus, and Mitsubishi vehicles
Supports repair of 2-terminal blower resistor circuits in rear or standard HVAC locations

Installation Notes and Tips

Verify terminal count, wire gauge, and connector shape against the original part before installation. Match the vehicle application carefully, since several listed fitments note multiple connectors required or rear auxiliary heater use. Inspect the blower resistor and surrounding wiring for heat damage before installing the new connector, and confirm a secure blade-terminal engagement after splicing.

Quality Assurance

Standard Ignition supplies this connector as an OE-style electrical service part for HVAC repair work. The brass terminals, plastic housing, and included harness components are selected for replacement of the original blower motor resistor connector in the listed applications.

This part fits 60 vehicles
