This causes the blower motor to run at varying speeds or not at all, or even to run continuously (not shut off). Changing the blower speed input on the climate control panel may have intermittent or no effect on the actual blower speed or operation. The most typical cause for these symptoms is a faulty blower final stage unit (commonly known as the blower resistor). PHOTO 7743 (somewhere in the copy, or as a lead photo) Later model BMWs (generally from the late ‘90s-on, with digital climate control panels) use a continuously variable blower speed control as opposed to the earlier models that have three or four specific blower speeds that are chosen via a control knob or dial. This continuously variable control is accomplished through a digitally modulated “final stage unit”. These final stage units do eventually fail and as noted above, the common symptoms may include; blower motor will not change speed per the climate control inputs, blower motor changes speed on its own when not in “auto” mode, blower motor does not operate at all, blower motor will not shut off. If your BMW is experiencing any of these symptoms, it may need a new final stage unit.
