    Default 02 Trailblazer A/C heater blower fan no work

    Hi folks, Trying to save my son in law a few bucks. The front blower fan doesn't work at all. I have taken it out and tried running it with 2 wires off the battery. Nothing doing. Is this a good way to test it or should it be done some other way? All fuses seem to be fine. It has the 4.2L engine and the fan control switch is digital?? As you can see, I'm not very familiar with the vehicle. Any input would be GREATLY appreciated. Thanks so much, Doug

    Most of teh time if the fan doesn't blow at all then it is the blower motor. I fit works but only on certain speeds or just the top speed it si the blower motor resistor.
