2000 Chevrolet S10 Question: Chevy S10 AC\Heater blower motor



jpgordy, 2.2L 4 Cylinder, Vicksburg, MS, November 14, 2010, 19:17

Why would my AC\Heater blower motor continue to run after shutting off engine and removing key from ignition. It will also operate intermittedly on\off at random while driving down the road? When vehicle is off and blower is running, the speed of the fan cannot be changed by the fan speed switch i.e. the speed stays at a constant rate of whatever it was set at when vehicle is shut down.

    blower resistor shorted to power. it is by the blower motor in the heater case.

    yep it's the blower. it has a clutch fan system for radiator cooling. thanks for the feedback though.
