How to Replace a 94 Ford Ranger Blower Motor Resistor Pack

The 1994 model year was the year when Ford began paying back Mazda for its production of the Courier -- the predecessor to the Ranger -- as Mazda borrowed Fords Ranger platform to build its own B-series pickup. The 1994 Ranger was a simple truck that came standard with only a heater as its climate control system, but did have optional air conditioning available. The blower motor resistor controlled the speed of the fan that circulated the heated or cooled air throughout the cab by regulating the flow of electricity to the blower motor. Replacing the 1994 Rangers blower motor resistor is a quick and simple process that nearly any owner can perform.
