DIY: Ford Ranger Blower Motor Resistor Replacement

Video tutorial on how to replace the blower motor resistor on a Ford Ranger. This is a fairly common issue amongst Rangers, Explorers, and most likely the Mazda B series trucks as well. The main symptom of a failing blower motor resistor is that your fan speed will only work on the high setting. If your fan doesn’t work at all, then there is most likely a blown fuse, issue with the blower motor, hvac panel problem, or a fault in the wiring. This particular vehicle I am working with here today is a 1998 Ford Ranger, so there maybe some variations between the years and models.
