This switch has only been in service for a few months. As summer came, I noticed my temperature was getting quite high, then the fan finally turned on. Then, for the next week or so, every time I stopped at a stop light or in a traffic jam, the coolant temp would get really high, almost overheating! Scared me to death. It took a bit of troubleshooting, but this piece of junk stopped working. This would barely provide enough continuity that my fan switch relay would go fast but would never trip…
