Bow Thruster Will Not Lower


We have a 1996 Santorin, which we have owned for 4 years. Recently, when we were leaving a marina, the bow thruster would not lower. We had just come into the marina 2-3 weeks prior and there had been no issue with the thruster. We tested all of the electrical connections and there is power going to all. Also, it will beep when the toggle is switched to the "up" position, indicating that the thruster is all of the way up. It just doesn't move at all when the toggle is switched the the "down" position. We are preparing to haul out in a few days and remove the thruster for maintenance. In the meantime, can anyone think of anything else we can check? We've looked through the documents and topics in this group and couldn't find this specific issue.
