Jacks won't work

Sounds like time to call for tech support. Your emergency road service, assuming you belong to one, should be able to help you out. Either they can talk you through it send mobile tech. We us Coach-net and have had good luck over the years, usually they get a knowledgeable tech on the line to prevent the costly mobile tech, but then. . .

Or, since you are drive-able they can get you into someplace that can resolve it.

I know, if you are like me that is the last thing you want to do.
