2001 Ford Escape....

I am having all sorts of weird electrical problems. All started when car radio stopped working after two year old shoved change into the cd slot (Change had been in there for at least a month prior to me removing it). I removed the radio to get the change out thinking that it might possibly work again. Well that didn't happen. Now everything seems to be going. Power door locks, windows and headlights only work when the car is on and the interior lighting doesn't work at all. Could I have loosened something when I removed the radio? or did the change cause a short? I have tried to also replace the fuses to no avail. Warranty is up so any suggestions would be much appreciated before a costly trip to the dealer is necessary.

Thanks,
Adam
