Everybody knows that you need a clear view to drive safely. However, the interior blowers (blower stages 1-4) on many vehicles are defective and have a restricted function, or even none at all. If cold air and rain then fog up the windscreen, this can quickly become a safety risk. The only solution is a working blower. For vehicles equipped with air conditioning, the individual blower stages are automatically controlled. If one stage of the blower fails, this is usually due to a defective blower controller rather than the interior blower itself. As the series resistor limits current flow most strongly at low blower levels, the blower controller can burn out.
Herth+Buss offers vehicle specific blower controllers in its Elparts range, including for Mercedes, BMW, Citroën, Peugeot and vehicles of the VAG group. The range is constantly being expanded.
