I've done a ton of searching for exact problems that other people have encountered but I just can't seem to find one with a cure to this problem I'm having.
The problem I'm having is for dome reason Sunday I drove my zj around doing my errands and I went home. Went to look the jeep with my key fob and nothing happened. 20mins later I go to leave again and key in the ignition, turned, chimes, starts then dies including my gauge cluster is blank(no power)

Symtoms are :
Nothing but the abs light appears on the gauge cluster to key on, start
Drivers door lock works but windows do not
Passenger doors are all dead.
E.mirror on drivers door works
Noticed my alarm light will stay lite with no flash.
Vic displays normaly
Radio works
Lights work
Interior lights work
Windshield/hatch wipers work
Door chimes all work.
Will not display codes or mileage or none of the gauges work.
I checked fuses and relays all seem to be fine.


Key tricks didn't work
Im stuck here guys and really could use some help please

 

The fuel pump primes to pressure forgot to add that

 

How old is the battery?

 

It sounds like what happened to me last week, replaced my battery and it fixed the problem
