Original Member Title: Cruise control doesn't work on my 2004 Sightseer 30B
This AI-generated summary may contain inaccuracies. Please refer to the full thread for complete details.
A member asked for ideas on diagnosing non-working cruise control on a recently purchased 2004 Winnebago Sightseer 30B on a Ford V10 chassis. Members focused on chassis-side electrical troubleshooting rather than Winnebago house systems, with suggestions to check for other failed functions, blown or tripped breakers, fuses, and possible wiring changes made by previous owners.
One member shared a similar issue where a misrouted power wire and a popped breaker affected cruise control...
A member asked for ideas on diagnosing non-working cruise control on a recently purchased 2004 Winnebago Sightseer 30B on a Ford V10 chassis. Members focused on chassis-side electrical troubleshooting rather than Winnebago house systems, with suggestions to check for other failed functions, blown or tripped breakers, fuses, and possible wiring changes made by previous owners.
One member shared a similar issue where a misrouted power wire and a popped breaker affected cruise control and another accessory.
Another suggested that if the horn or steering-wheel-related functions also fail, a broken clock spring could be involved.
Several members recommended locating Ford chassis repair information, checking chassis fuse panels, or asking in Ford motorhome chassis resources since Ford systems may not be fully covered by Winnebago documentation.
The discussion did not identify a confirmed fix, but it narrowed the next steps to Ford chassis electrical diagnosis and related steering wheel controls.

Anything else not working? I found one of the bat lever breakers under the steps popped, wouldn't reset. Tracked down a power wire screwed to the firewall and when I got it where it belonged, the breaker held, and I got my cruise control and my power drivers window back! These older rigs I'm afraid there's potentially been a lot of electrical foolery been going on over the years...
The problem of sorting the wiring on RV is that we get semi-good info/support from Winnebago on their part but since they buy stripped chassis for the "truck" part they leave support for that to fall back to the chassis builder. And that becomes a problem as car/truck dealers are NOT inclined to help us DIY repair things!
My route would be to try searching out a repair manual for the Ford chassis you have. First thought might be to call a library on the odd chance they may still have one for that year. Second idea but I feel less likely is the auto parts store. I think they will tend to have newer but maybe get lucky?
Getting info on the chassis is sometimes a trek as they hold that info pretty close, so we have to get tricky! There MAY be somebody come along here that knows the details of cruise on early 2000's Ford truck, but it might take a long time before they look in!
Not trying to send you away but it may help to also post on some of the auto/ truck type forums as a place where you might find a gold mine of folks more interested in chassis question?
Cast a net in lots of different water?
For my limited knowledge of cruise I would have to start with looking for a fuse panel that involves chassis items. Likely to be found out under the hood, I would guess? No chassis manual on hand to guide you on that? Maybe a label inside the cover as a help?
On the other hand, I did a second check for manuals online and fidn lots of hits that seem interesting! Some for free, some to buy and I have no idea on what you may find but this is one that would seem to cut the chase and no idea of price.Just an option for quicker and likely more reliable info?
Lifes a gamble but we have to lay the chips down at some point, right? How much price versus value is often not known!
