2013 Ford Explorer battery goes dead over night Sign In

I have a 2013 Ford Explorer 3.5L engine with 113,000 miles on it. Just bought it about 3 months ago.
If it sit for 10 to 12 hours the battery goes dead. I have replaced the battery and had the alternator tested. I let it set for an hour.
There is a 2.5 amp draw on the battery that will sometimes drop to .03 amps for about 5 seconds then will return to 2.5 amps then may drop to 1 amp for awhile. It keeps changing. I have set the door switch by triggering the latch in the door and put a clamp on the switch for the hood. I have tried removing fuses and relays to isolate the cause of the draw but so many things are drawing current it never drops below .7 amps. fuse 28 is drawing the most. It is for the audio and GPS. I also have disconnected the alternator and the ignition switch which made no difference.
Any help or suggestions would be greatly appreciated. I am at my wits end. Sometimes the dash lights come on for no reason. I happen to be outside at night and noticed them on.

The dash lights are a good hint. Ford uses a lighting control module usually mounted under the dash on the driver's side. I would try unplugging that before you park it overnight.
