A clarifacation on this previous post. The A/C WILL cause the fans to run continously ie, as long as the compresser is running the A/C circuit will override the otterstadt switch and run the fans. When the compressor stops if the otterstadt switch isn't hot enough then the fans will stop. (Fanzilla changes this a little.)
