Noticed clicking every 3 minutes, next day battery dead, aaa guy said needed new battery clicking didn't drain it - bad battry, got new battery and clicking continued and now dead battery again.
AAA guys dont fix car, they rescue them....
the door lock system is broken
you have 2 choices. may be 3
#3 may just be a fuse pull, ill look that up now for you. ....lets see...
at alldata.com.
what id do.
id check all fuse first for blown, with an ohmmeter, 0=good, infinity = bad.
then id pull all the door relays. in the main junction box.
is the battery drain gone (i use and ammeter to find that truth)
THE BCM (body control module ) runs the locks, so you can just
pull its fuses.. or other things die.
keep in mind that door locks are alive , keys in pocket.
so that begs the question, is the BCM messing up (or relays stuck)
or is the BCM being told to open a door, full time ?
id connect any scan tool to the OBD2 conn. and see if there are fault codes. (like relay stuck door, etc)
stuck switch for doors."called door lock switch mux" by Jeep.
The BCM has many relay that it controls, pull them all and see
which one is causing the DRAIN, key off
and work backwards from there.
the BCM has RKE data line, this is the remote key receiver.
if it goes nuts it might seen door commands to the BCM full time.
so unplug it, to see if the commands end.
its called the RKEM (m for module)
the problem focus is the BCM is the brain that runs it all.
it has inputs and outputs.
the brain (processor) can have a bad input (switch or RKE)
or the output can stick (prime target door relays)
that is it .
i cant find the JB B+ hot feed, drawing, there are over 50 pages on this JB. a real FSM would win here. to find the door power actual feed .
such is life, in newer complex cars....

you have something thats staying on with power when you shut the car off,first check all lights glove apartment,underhood,in trunk ,just because ther closed doesnt mean the light is off,check your car at night it might help to see the lights,if not another way is to take a multi meter to the battery and while some holds the meter pull out fuses in your fus box one at a time to see when the meter makes a change,this will help you to narrow down whats staying on and draining the power from the battery,if this helps please give me a fix ya vote

The Module in the Drivers Door is notorius for this problem. I would start by changing that first. Good luck to you. Thanks for using fixya!

Unit has a draw somewhere that needs to be addressed. I have found the auto starts sometimes can cause this. But if the draw is through the negative side it could be tough. You should take it to the dealer and have them perform a draw test on the entire vehicle.

Your security system could have a problem, replace battery in keyless remote. If not helping you may have to take it somewhere and have security system checked
