Review on Manual Control Blower Resistor Classic by Bob Berry

This product is definitely a game-changer! As my tests showed, the manual control blower resistor improves the efficiency of the engine cooling and climate control system, providing optimal heating and cooling... The installation process was smooth and easy. The only letdown was the lack of clear instructions in the manual. However, this did not hinder the superb output of the product. Overall, highly recommend the product for any automotive owner who wants to improve their cars climate control system..
