IntroductionA common symptom of a faulty blower motor resistor is a blower motor that is stuck on one setting. The blower motor resistor is the component directly responsible for controlling the blower motor fan speed. If the resistor shorts or fails, it may cause the blower motor to remain stuck on one fan speed. The heating and air conditioning systems may still function at one speed, but the resistor will have to be replaced in order for full functionality to be restored.ApplicationCompatible for BMWCompatible for BMW 3 Series E36 1991-1998Compatible for BMW 3 Series E46 1998-2005Compatible for BMW 3 Series E46 M3 3.2 2000-2006Compatible for BMW 3 Series E46 M3 CSL 2003-2006Compatible for BMW 5 Series E39 1996-2004Compatible for BMW 5 Series E39 M 4.9 1998-2003Compatible for BMW X3 E83 2004-2010Compatible for BMW X5 E53 1999-2007SpecificationOEM & Part Number:6411 6 923 204, 641169232046411 6 920 365, 641169203656411 6 929 486, 641169294866411 6 931 680, 641169316806411 8 383 835, 641183838356411 8 385 549, 641183855496411 8 364 173, 641183641736411 8 377 579, 64118377579Condition: 100% brand newWarranty: one year warranty for any manufacturing defectQuantity: 1 x Blower Fan ResistorYou will get products exactly as shown in the picture aboveNote- Please double confirm compatibility and OEM number before purchasing, Please confirm your old part number matches one of the above part numbers- Professional Installation Is Highly Recommended (No Instruction Included)- Please check our shop for other auto parts you may be interested in.- Please leave us positive feedback and we would appreciate it very much after receiving your order with satisfaction.
