    hi, yesterday my blower motor stopped working on all 4 settings.
    today i removed the motor and bench tested it, with 12v applied it spins up perfectly, the fan also spins easily by hand.
    so i tested the electrical connector that plugs into the fan, onb fan switch position 0 there is 0 volts, on fan switch positions 1,2,3,4 there is 1.7v going to the connector, shouldnt there be 12v going to the connector ?
    because there is some power 1.7v going to the connector does that rule out fuse/relay problems or highlight them ?
    there doesnt seem to be enough power going to the connector to power the fan.
    it worked perfectly yesterday morning.
    can anyone help ?

    I have connected vcds which says there is no fault codes.
    Tried doing a output test in the HVAC controller but nothing is happening.
    But in measuring values it does show the heater to be turning on and off when I turn the heater knob from position 0 to position 1.

    With my very limited electronics would the switch not be switching relays where the higher voltage resides.
