I have a 2016 Wildwood 26tbss that has remote control for everything. only 14 months old and only been on 2 short trips. The outside switches do absolutely nothing. Have to use the remote. well, this morning while packing up, the remote stopped working the stabilizers. I had to manually crank them. at home now and found bad fuse on board under the fridge. My questions. 1. what would cause the 20 amp fuse to blow? No loose connections. 2. where should I start on finding out why outside switches do nothing? Any help is appreciated.
