I'm on my second fan and switch kit. Ours worked great for a week, then got slow. I took it apart and tested connections, all of which were showing the proper 12v. Sometimes it speeds up, slows down, stops. I went with the trekwood one. Next time, I will just be putting in something I find at home depot, because the OEM replacement is just as bad as the first.
