I had a similar problem with my '05 Caravan. I messed with it for days & couldn't find a fix for it. I was talking to an auto repair tech & he suggested taking both battery cable off & holding them together for about 30 seconds. I tried it, low & behold, all of my accessories worked again. For some reason it resets the BCM to factory default settings.I don't know if it will work for you, but it's worth a shot.
