Review on 🔧 Enhanced Performance: Standard Motor Products RU344T Blower Motor Resistor by Erik Snyder

Perfect replacement for Chevy S-10/GMC Sonoma fan motor resistor. However, after replacing this for the second time in 6 months, it occurred to me that something else is wrong. I checked the fan motor and found it to be very sluggish from years of wear, dirt and corrosion. I realized that the extra load on the fan motor was causing the fan resistor to repeatedly overheat and burn out. I replaced the fan motor (also available from Revain) and have had no problems since. I also sleep better knowing I won't start an electrical fire in the engine compartment. If you've replaced the resistor more than once, do yourself a favor and check the fan motor yourself. Please note that replacing the fan motor in these vehicles is a pain. To get to the bolts on the engine case, there are a few things that need to be removed/moved. Even with the ECU and coolant reservoir removed, you'll still need extension cords or small hands to get to the bottom screws.
