i was messing with power mirrors and i crossed out a wire....heard a crack under the dash...now over drive off light flashes on..no radio..no power..but it starts and idols fine..could it be the pcm...(computer)..anyone have an idea,,,please help.....thanks

I would check the fuses....maybe one of those blew.
I am not familiar with the wiring on the newer windstars, so I cannot give more help.
Your owner's manual, or a repair guide should give you a listing of what is on each circuit.

i have tried this..took out every fuse...and its still not workin right......any more ideas.....
