We have a 2013 Class C on a Ford E450. I noticed the other day when my wife was backing up the motorhome that the back up light on the left side (drivers) was not working. I thought the bulb was burned out and remove the cover to that light. Pulled out the bulb and it appeared to be ok. Put bulb back in and it still did not light up. So I replaced the cover and would deal with it later. The next day I went out there and hit the outside of the light cover and it came on as it should. But I noticed that the brake light there to the right of it would not light up when the brakes were applied. The tail light part would work however. I assumed that one of the filaments of the bulb was bad and the bulb needed to be replaced. I had to remove the entire light from the RV in order to get access to it. I noticed that one of the screws had a broken head and there was a tiny gap between it and the RV. When I pulled it off entirely, I could tell that water had been getting down in it. I pulled the bulb and it appeared to be good. Switched the bulb with the good side and still the same thing (not the bulb). Any idea what could be the issue? Below is a picture of what the back of the RV looks like. The light in question is on the rear drivers side. The clear cover comes off without removing the entire light from the RV. However, to get to the two tail lights, I have to remove the entire light. I was able to get another screw to pull the light housing in to the rubber gasket and seal it good. Once I get it all workign correctly, I'm gonna run a light bead of silicon around it to make sure it stays water tight. Funny thing is that it just past inspection with CW....lmao
