Can anyone give me some direction with a strange electrical issue pls.

2013' 3.5 XLT has no electrical power except for radio and accessory plug on the dash. All other power is dead.
1) battery is at approx. 12.58
2) checked related fuses ( both engine & interior fuse boxes)
3) Also tried to jump it ( just in case of a ground issue)


Prior to dying, started it up & backed it up about 5 ft then shut it off. Next time I got in... dead.


I don't know how to check for a bad relay & curious if it is some type of Security kill switch??


Thx in advance,

 

so nothing but the radio, and 12v plug?
no horn, no cranks, no lights in or out, no door locks...?

 

not sure what these are...some kind of fuse....
maybe why nothing works as its two lines going to power other stuff...

 

fusible links

 

lol...thanks....the links.....still weird on the op's problem....not sure if they would pop like that....

 

I've only seen those pop when someone reverses the booster terminals, be nice if the op replied

 

yes,


#3 say he tried to jump it...?????.
boosting or jumper wires....

 

I assumed that was after the issue, also jumping won't find ground faults


booster pack or jumping cables

 

Thanks for the Input & sorry for the delay. First ( I unhooked the battery cables, sat for approx. 15 mins. When I reconnected, heard a click in the fuse box and all electrical came back on with no issues.




I would still like to address a potential intermittent issue but currently things are running normal.


For future reference & to address some of the questions:


I lost everything except
1) Radio ( which played with no key in ignition and doors open)
2) 12 V Accessory
3) power seat
4) Horn
no locks, lights instrument panel etc.


Battery cables were on the correct terminals. I was concerned about disconnecting them that it may erase the error codes but I expect it didn't.


I am going to take in it and have it scanned to get some specifics and will reply with what I find.


Thanks again for your input.

 

now that we get more info... I wonder, my gmc canyon did something similar when my battery connections got corroded ....door locks/power windows and my radio and key fob..wouldn't work for 12-24 hrs after, time for the bcm to reboot I guess..


waiting to see what is found out...
