The blower final stage fan resistor is known to fail. Symptoms are the heater fan speed varies regardless of the setting, the fan will not turn off when the car is switched off, or the fan will not switch on at all.

    fan doesn't work well, and now it runs even when everything is off, causing battery to discharge

    When the car is turned off you can hear the fan running and cutting off by itself.

    AC fan worked intermittenly, sometimes would come on at reduced speed & sometimes won't come on at all.

    Blower will not come on. Sometimes it works when I leave the setting on high. Sometimes it works if I turn off the car and turn it back on again. Today neither worked.

    It's freezing cold out and when I try to turn the heat up it doesn't blow any air at all. It works when it feels like it, I hit bump and the blower kicked on but started the car the next day and it doesn't want to blow any heat once again. I'm wondering if it is the blower motor "resistor"?
