Electrical components can be the first to wear out and stop functioning properly in your early model Mustang, which is why CJ's provide the Heater Blower Motor Switch Resistor for 1965-1966 Mustangs and 1967 Mustangs without Air Conditioning to get your cabin temperatures back to normal. This resistor will improve and regulate the flow of the current into the motor, ultimately regulating the speed at which the heater blower motor runs. Directly replace your factory original heater blower motor switch resistor with this OE-style replacement that installs directly onto the heater box.
Features and Benefits:
- Direct-Fit Factory Replacement
- Current Regulator
- Maintains Comfortable Cabin Temperatures
