Universal Conditioner SW 9967C Resistor Review

The Universal Conditioner in this category was ineffective on my automotive. Based on my observations, it did not improve the engine cooling or climate control. It may work for some people's vehicles, but it was not successful in mine. The only pro is that it was easy to use. The con is that it did not live up to its advertised benefits. I would not recommend this product for engine cooling or climate control replacement parts.

Worked great on my 92 Corolla. Only two speeds worked before the replacement: low and high. Now they all work! Awesome easy to replace (1 screw and quick release plug) which takes less than 5 minutes.

I installed a resistor on my 1988 Corolla 4 door sedan. It was a quick one screw install and quick wire connection after I removed the glove box/trim with five screws. The hardest part of the installation was finding the existing resistor (at the end of the bare wire) which was at the bottom of all the air ducts near the passenger side floor. All fan speed switch settings now work properly.
