On Saturday, after getting back from the lake, I went to back the boat in the garage and guess what? It had other plans. This was after putting in and taking out, and backing into a buddies driveway not 15 min. earlier. Only fitting for the kind of day I had. Anyway, I disconnected the trailer lights/adapter and used the manual blockout. I have checked the connections, fuses, wires, fluid, lights, etc. and havent found the problem yet. The trailer brake lights work so I assume the adapter plug/wires are fine. Is there anything else someone could recommend to try? I dont want to let it sit at the shop if I dont have to. I think it might be the solenoid; would this be covered under warranty? Its an 07 and I think it has a 5 yr. warranty? Thanks
