Berkshire Exorcism??

So, I'm in a rest area on uphill side of Donner pass in California last Friday evening, getting pounded with rain all night.

Get up next morning pull in the slides, etc and get ready to go. Switch the wipers on...... Nothing. Check fuse (getting soaking wet) and it's OK. Then the wipers came on by themselves, but the over head defogging fans shut down.

Then the external step extended all by itself, but the overhead fans came back and the auto door lock on the refrigerator cycled lock to unlocked several times, also all by itself and then the step retracted again.

This Kabuki Dance when on for several minutes and I wondered if the damn coach might have been possessed; I was waiting for the DW's head to spin around and around, but thankfully that didn't happen. All the above items happened several (in random order) times, with myself or the DW not touching ANYTHING.

I finally just drove off, and gradually everything started working normally again. Obviously, something was really "hosed". Trouble shooting will be tough since it's been fine for several days now. But I'm thinking something intermittent in the ignition switch.

Any other possibilities?? Like an electronic module or something of that nature??

Boowho??

Wild guess is you have moisture getting into the electrical box where all those items originate. Don't think it would be the ignition circuit tho.

Purely from a historical standpoint, Donner Pass would probably be the last place I would want to get stranded.

You never had thoughts about eating your wife with fava beans by any chance?

It does sound like you may have had some kind of water infiltration in the power system somewhere. I don't know how that would make the steps extend on their own, but I have read other posts where this has happened.

Yeah, I've been over Donner at least 6 times in my life, but never anything like this before. I too believe that it may have been caused by moisture, but would love to know WHAT component was affected. That way maybe I could seal it better.

Thanks all......

So I may have sol-ved the problem

Just noticed that the cover to the engine diagnostic plugin point was not attached.

Probably left loose by the guy that reprogrammed my computer (odo/speedo) for the new larger tires a couple of weeks ago.

I'd strongly suspect that a LOT of rain water gets sucked into the rear radiator grille.

Boowho??

Good that you figured it out. That could cause problems from corrosion if not corrected. I seem to be having electric issues my self like steps retracting with the switch off. All the power point fuses blew in one hours time. I suspect this pos Rand McNally 7710 GPS to be the cause of that? Lights not working and bulbs burning out in the last week or so.
I'll check the cover first thing in the morning.

My RVND7710 adapter shorted out the fuse to the Radio, map lights and cigarette lighter outlet. Seems to be a design problem from Rand McNally. Contacted them and they sent a replacement. The issue with the original is the inside plastic breaks rather easily and when plugged into the cigarette lighter outlet makes the spring metal clips come in contact with the metal ring on the end of the fuse.

Thanks for the info. I will call them this week. I don't know what everyone else thinks of the. 7710 but I'm not a fan. I bought it at General RV at a RV show and tried to return it after first use. They wouldn't take it back. I don't blame them but I still feel stuck with a product that wasn't well designed.
Thanks for the heads up on the cord.
