My 1994 Ranger with a 4.0l and factory air conditioning blower Motor Resistor pack has failed and I need to replace it. It is not on the blower housing as shown in every diagram I can find. One on line source says there are no diagrams from Ford showing the location of the resistor pack in this particular engine/AC combination. Does anyone here happen to know where the resistor pack for this particular installation is located. There isn't much room at the firewall area and it is difficult to access any hint would be a great help.
