B0601
Blower Motor Resistor Circuit
1997-2000 BMW 528i E39 2.8L I6 🇬🇧
Low SeverityBody
Description
Malfunction in the blower motor resistor or speed control module. The resistor controls blower speed at lower settings.
Symptoms
- Blower only works on highest speed
- No blower at low/medium settings
- Blower speed inconsistent
Common Causes
- Faulty blower resistor
- Thermal fuse in resistor blown
- Corroded resistor connector
- Excessive current from failing blower motor
Diagnostic Steps
- Test blower resistor resistance at each tap
- Check thermal fuse continuity
- Inspect resistor connector
- Measure blower motor current draw
Repair Notes
Replace blower motor resistor. If resistor keeps failing, check blower motor current draw as a failing motor can burn resistors.
