I know this sounds crazy, but.......
My 2004 T&C with 265,000 miles runs great, the problem is when it rains.
I will be driving and the wipers, radio and ac blower cut off.
I can stop the car, turn the key to accessories or on and everything works.
Then I start the car and they are off again.
This does not happen every time, and has not happened for a while until yesterday, snowstorm, and they cut off.
After a while everything will start working, but usually only for a few minutes.

I go out this morning and warm it up and works fine, drive about two miles, off.

Anybody with any ideas?
It is crazy that I can turn the engine off and everything works fine.

 

Looks like you've got a bit resistance in there. First port of call is the fuse box or IPM. Isolate battery and check all connections on underside of IPM. If you find corrosion your getting somewhere.
