METZGER 0917112 Heating

Product Overview

The METZGER 0917112 Heating is a high‑performance interior blower resistor designed to deliver reliable heating and airflow control in automotive cabins. It serves as the critical component that regulates the electric current supplied to the vehicle’s interior fan, ensuring optimal temperature distribution and comfort for occupants.

Key Functionalities

• Precise Current Regulation: The resistor limits the electrical load on the blower motor, preventing overheating while maintaining consistent fan speed across varying voltage conditions.
• Enhanced Heating Efficiency: By providing a stable current path, it allows the heating system to operate at peak efficiency, reducing energy consumption and improving cabin warmth.
• Durable Construction: Built with high‑temperature resistant materials, the resistor can withstand prolonged exposure to heat generated by both the blower motor and the vehicle’s HVAC system.

Compatibility Matrix

The METZGER 0917112 is engineered for a broad range of European vehicles, particularly those from Citroën and Peugeot. Its specifications match the electrical architecture found in models such as:

• Citroën Xsara
• Peugeot 206 (including 3/5‑door, SW, and CC variants)
• Citroën Picasso
• Other vehicles equipped with a standard interior blower system that requires a resistor in the range of 0.8–1.2 Ω.

Installation Guidelines

1. Safety First: Disconnect the vehicle’s battery to eliminate electrical hazards before beginning any work on the HVAC circuit.
2. Locate the Existing Resistor: The resistor is typically mounted near the blower motor housing, connected by a pair of wires that carry the power supply and return current.
3. Remove Old Component: Carefully detach the wiring harnesses from the old resistor. Note the orientation and connector type to ensure correct reassembly.
4. Mount the METZGER 0917112: Position the new resistor in place, aligning it with the mounting brackets or screw holes. Secure firmly to prevent vibration damage.
5. Reconnect Wiring: Attach the harnesses exactly as they were on the previous unit, verifying that polarity and connector alignment match the original configuration.
6. Test Functionality: Reconnect the battery and activate the HVAC system. Observe fan speed and cabin temperature to confirm proper operation. The resistor should maintain a steady airflow without excessive heat buildup.
