I have a 2015 Sunseeker 3010DS. The other day my wife noticed while driving behind me that the turn signal and brake lights only worked on the passenger side of the MH. I am concerned as we are leaving to go down south in a week. I am not very knowledgeable in electrical issues. I have replaced the bulb for the turn signal/brake light on the driver side but that has not fixed the problem. Thanks in advance for any help as to what the solution would be to fix this issue.
I had a 1996 E350 with similar problems. It would work then not work. Sometimes just the brake lights sometimes directional and sometimes both. It turned out to be the integrated module on the steering column where the 4 way flasher switch is. Everything goes through there and they haven't changed it much. My 2016 e450 looks the same. I had this diagnosed/repaired at my RV dealer and glad I had a tech that had worked on these a lot. Only took him a couple of hours to track it to that. Of course since it was nearly 20 years old, we both were think bad grounds or mouse chewed wires. With yours being so new, I wouldn't think it would be that but you never know.
