Standard Ignition S2452 HVAC Blower Motor Resistor Connector - Front

HVAC Blower Motor Resistor Connector for Mercedes-Benz and BMW

Standard Ignition S2452 is an HVAC blower motor resistor connector built for select Mercedes-Benz, BMW, and Maybach applications. It features a black plastic rectangular housing with brass bullet terminals and a 2-wire, 12-volt layout for direct electrical connection at the blower resistor circuit.

Key Features

• Standard Ignition S2452 HVAC blower motor resistor connector
• Male connector with push-on attachment method
• Black plastic rectangular housing
• Brass contact terminal material with female bullet terminals
• 2-wire, 12V connector with wiring harness included
• 6.5-inch wiring harness length for repair and replacement work
• Includes splice connectors and a 2-wire harness for service use

Product Details

This Standard Ignition S2452 connector is used in HVAC blower motor resistor repair work where the original connector has heat damage, corrosion, or broken terminals. The 0.875-inch connector body uses a push-on design and 12-gauge wiring to support the electrical connection at the blower resistor. This part cross-references PT2437 and EC2353 for the same application. It is a practical replacement for Mercedes-Benz E-Class, S-Class, SL-Class, and BMW 7 Series and M3 blower resistor connector service.

What It Helps Fix

• Melted or heat-damaged blower motor resistor connector housings
• Intermittent HVAC blower operation caused by poor terminal contact
• Corroded or loose electrical connections at the resistor plug
• Broken wires near the blower motor resistor harness
• Loss of blower speed control in the HVAC system

Installation Notes and Tips

• Verify connector shape, terminal style, and wire gauge before installation.
• Match the vehicle side and HVAC resistor connection before cutting or splicing.
• Inspect the blower resistor and surrounding wiring for heat damage before installing the new connector.
• Use proper electrical repair practices when joining the included harness and splice connectors.
