Well guess who just ran out into his driveway and tried to turn on turn signals...only the hazards will work and dashboard will flash with signals..With ignition off, the signals don't work at all...It looks like they have the power tapped off of the hazards or something in your coach to get them to act that way. But since everything works, I'd let it be until something really does go bad. With my luck, I'd end up breaking two things while fixing one..(If it wasn't for bad luck, I wouldn't have any)...Obey the 11th commandment, if it works, don't fix it....I just wish there are times I would follow my own advice.....
