    Default 2000 Dodge Grand Caravan HVAC Fan only works on High

    Hello, I have seen this posted before but cannot find it now. A friend has a
    2000 GC 3.8l auto, and the HVAC blower will not come on unless it is set to
    high, none of the lower speed settings work. He was asking what the possible
    causes were and if it was easy to fix. The he thinks rear blower control is
    working right. Any help is appreciated.

    I know nothing of the GC, but in general with vehicles, a blower motor
    that runs on high speed only means the speed control resistor pak is
    burnt up. Often it is because the blower motor is wearing out and is
    pulling too much current. You could try replacing just the resistor
    pak, but if the new one blows in a few days or weeks, then you would
    need to replace the blower motor (and the resistor pak one more time).
