Unplug the blower motor and, using a 12 volt DC test light ,see that the blower motor is getting power. The test light should light up in each of the positions of the fan speed switch. Becoming brighter as higher speeds on the switch are selected. If you have no power at the blower motor unplug the resistor block. Test for power there. Only one terminal will have power depending on the position of the fan speed switch. If you have power at all terminals, individually, but no power at the blower, resistor block is bad. If you have power at blower motor, blower motor is bad. If you have no power anywhere, switch on dash is bad. This is assuming you checked the fuses and they are all good. HTH. -Jim
