This is absolute Nuts!

Hi all,
Today we had a rain storm. I drove my 2001 chrysler voyager with 85000 miles on it from PA to NY in the rain. It was really pouring and just out of the blue my wipers, radio and blower went dead. I pulled to the side and turned off the van. I tried the wipers and it worked. The radio also came back on. I started it and they went back off again. I turned it off and the radio and wipers came back on again. I tried this for a few seconds till I got it to work with the van running. I started off down the road and the engine light came on. Then I noticed that the van seemed to be stuck in low gear.... Dreaded Limp mode. I pulled to the side again and turned it off for a few seconds and then it worked fine. I took it to autozone and and they found P0700 twice and P0725 error codes. I asked the guy not to clear the codes since I wanted to have a mechanic look at it. Driving back to Pa the engine light just went off. Strange!!!! Never heard of this before.
Also i noticed that once I start the car, it kinna strugles when you first mash the gas. Must be bad gas...

Please, if you have ever had this experience or can shed a little light on the matter I would really apreciate it.

Thanks

yes i crossed this path a few times and normaly the wiring harness ends up feeding voltage migration through the pdc (fuse box under hood) and feed excess voltage after harness gets wet the wire that gets affected is the yellow wire in cavity #8 at the trans controller this wire should only have battery voltage on a crank if any voltage migrates to this wire after it's running it will shut down the acc relay and only needs about 4 volts for this to happen so if you connect a small 12 volt lamp on this wire it will light up on a crank then if any residual voltage comes around it will burn it off otherwise it's a harness replacement this works done it many times

Is this expensive? Do I need the dealership to do it?

the dealer may want to replace the harness just pick up some small 12 volt lamp 2 wires you ground one and connect the other wire to the yellow wire i described in the previous post

Thanks, I'll try it.. But one question. While i believe that the short may have caused the sensors to act up, what made the check engine light go off? It is still working cause it lights up whe I turn on the ignition but there is no instance of a fault again.

the vehicle is built with certain software in the controllers and one is the controllers need to know when the starter is engaged this info deters the controller of putting a eronious code in now if the engine is running and this particular wire bleeds off a little voltage into the controller at the same time the controller gets very confused then will spit these codes out for no obvious reason

I'll give this a try and post my results. Is there anyway to get arround this other than a harness replacement.

Thanks for your help..
