It refers to the number of electrical contact points on the unit, ensuring it matches the specific electrical architecture of your vehicle's blower circuit.
No, it is an OE-specific part. Always verify your specific vehicle's compatibility via the MPN ABR 71 000S before purchase.
Yes, it is covered by a 2-year or 30,000-mile warranty against manufacturing defects.
If you are comfortable with basic automotive electrical work and interior panel removal, it is a manageable task, though professional installation is recommended.
A clogged filter forces the motor to work harder, which generates excess heat and can lead to premature failure of the new resistor.
Yes, Mahle is a globally recognized manufacturer that supplies components to many of the world's leading vehicle makers.
This is a classic sign of a failed resistor. Replace the ABR 71 000S with the new unit.
Check the blower motor fuse and the electrical connection to the resistor. If power is reaching the resistor but not the motor, the resistor may be the cause.
Inspect the wiring harness for signs of melting or loose terminals, as these can create poor contact at the resistor plug.
Installation of the ABR 71 000S typically involves accessing the HVAC assembly, often located behind the glove box or under the passenger side dashboard. Always disconnect the negative battery terminal before beginning work to prevent electrical shorts. Verify that the harness connector is free of corrosion before plugging it into the new unit. For long-term care, ensure that your vehicle's cabin air filter is replaced regularly; a clogged filter places unnecessary mechanical load on the blower motor, which can cause excessive heat buildup and prematurely fail even high-quality resistors.
