To cut the chase, we may need more precise info on what lights are/are not working? If
left side lights are working, that will put it out of the controls, etc. and you don't need to consider them.
I think I read that the right turn signal and right brake lights are not working? But left side are working? I like to start with the right ideas!
If that is true, it leads to the thought that there are two different problems. That can sometimes mean it is a ground that is shared, or perhaps one bulb which does both jobs?
It can get confusing if we have one bad bulb or one filament in a bulb and the other bulb may have corroded contacts or such?
I tend to go for the meter to check things like that. First do the bulbs have good continuity from the point where power goes in to where it comes out to ground? I tend to scrub the contacts on something mild like rough cloth to help make sure they can work.
If the bulbs appear good, how does the bulb holder look?
If it is corroded, I do some cleaning or possibly go to sandpaper to clean them to make good contact. Sometimes a pencil with sandpaper wrapped over the end is good to do some gentle cleaning of that contact down in the base where we have a hard time reaching. Not so rough that you wear the contact off too much!
But if not solved, I have to go looking at battery and ground getting to the bulb holder contacts at the right time. Don't fall into the trap of looking for battery on a light without turning that light on! But if you do, I can assure you it will not be the first time it's happened!
As a guide to help sort where to find that battery and ground, Winnebago stamps their part of the small wiring with ID labels near the ends. On fixtures like taillights, you have to pull enough wire out to get past the point where Winn connects to the fixture wires!
Those codes are usually two or three letters at the end of a long string of code.
To decode that ID for "from" and "to" locations, we have this chart:
Sorry, for whatever reason, they have changed this chart and it is no longer "searchable" by hitting cntl and F! That makes it more of a drag to scroll through pages and pages to get to what we need!
We can get the basic drawings for the rear lights here, but I suspect you actually have a 31 foot, rather than a 33?
A snip to help with ID?
Quick notes shows the left and right are the same ground and most of the battery code is the same for both sides except for the turn signals which do have to have different feeds for SC and SD as those are the turn signals!
