I want your Best (& Most complete) recommendations for a Electric wiring diagram book or source for a fully loaded 2010 Dodge Grand Caravan. Haynes has a good supply of diagrams & I do also have the factory user manual. What I'm researching to solve the ghosts in my system are the horn & wiper circuits. The previous (1st) owner decided the problem (ghost) was in the horn circuit & pulled those fuses. All was fine or so it seemed. I learned to Not put the key in my pocket. So many buttons & so many possibilities. Still, only my pocket knows how to lower the front door glass from afar. At least the horn can't honk randomly.

OK. There is battery drain to the excess. I bought a new battery & beefier terminal posts. Not ready to install them because I'd prefer to exorcise the ghosts whilst the system is completely dead. The wiper ckt? I can only think of this as a clue. When my charger kicks in the wipers jolt just a fraction of movement. Can't be good for the motor that drives them. HELP with service manual sources etc.

Thanks!

Somehow this does not seem to have posted yet (& I thought I hit all the right buttons). I have an update from both our local Dodge Parts & Service people. That information is only available online from The Chrysler internal people source. No, I am not worthy. The worthy people are Not qualified to anything more than spend My money (But Only) as directed by their Service Manager. Did I mention I hate new cars?
