From ignition switch via relay
Power comes from the ignition relay via the key switch.
The relay also powers several other circuits. The key switch activates the relay so that those circuits are not powered directly from the key switch.
SOURCE: blower motor doesn't work and has no power to it
Check the blower multispeed control resistor pack is not faulty.
The resistor pack is usually located in the air ducting, in the blower fan airflow.
Basically, +12v power is supplied (via fuse) to the fan speed control switch, which then passes via the selected speed control resistor, to the fan motor. Often a interface relay is used to switch the blower motor high current.

check if there is any voltage reading at the fan blower wiring when activated,if there is an it still does not work then you may need a replacement blower...

check the wiring to the reostat (the resistor that controls the fan speed) also check the reostat has not burnt out. (the reostat should be near the heater motor housing)

Did you find out a solution to your problem? I have a 1996 trooper that is showing most of the same symptoms that you have. I'm curious as to your fix. Was it simply a bad ground?
