Another source of help would be the minivan forum at allpar.com
Sounds like another problem with the Chrysler Totally Integrated Power Module.
I suggest you find out where the common source of power is to the devices that are having trouble and check the connections in line with that power source. There is most likely a bad connection to power somewhere in that line. Tapping lightly on suspected areas with a screwdriver handle may help show up the problem spot.
