'93 850 heater motor won't run

    Today I discovered that my battery was dead after 10 days of non-use
    and that the heater fan motor won't run. Lights blink on the control
    panel to indicate a problem and fault codes 4-1-7 and 4-1-8 come up.
    4-1-8 seems to be the likely one indicating a lack of "control signal
    to blower fan power stage". Anyone know what that means? What the
    actual problem might be? This is the electronic climate control
    system and all seems dead except for the recirculate and AC Off
    lights.

    Any ideas would be much appreciated. I assume that the dead battery
    is a separate issue (like the broken left glove compartment hinge
    possibly allowing the light to stay on).

    Thanks---Jay Hale

    Asuming you are checking B1 code 417 stands for "temerature sensor fan on
    passanger side blocked".

    Clear al faultcodes with a fresh battery in the car. If you install a new
    battery they might be reset alredy.
