Jeep Gladiator Dash Electronics Flipping out

Like I said on post #10, the first thing I did was check the battery cables to make sure they were on tight and then checked all my ground bolts - the two on the frame and the ones on the fender just in front of the battery. After that and with no change, I pulled the main battery and checked my PCM connections as well as the leads on the auxiliary battery. All checked out.
Did my best to check what I could and so far, nothing looks loose.
HA! Moby has some issues of his own too
Yeah, first thing I checked. A real pain in the ass.
Sorry, which one is that? LOL Been checking everything I could.
As I stated earlier, I only removed the top AFTER I had this problem and wasn't able to find anything obvious. Nothing is loose there.
Well damn, I do remember that. When you had this problem, did you have other issues as well or just light blinking?
Just an update on things. Did some research and found that after disconnecting the battery for a long time, the Infotainment system can really get out of whack and do a lot of what I was seeing. I also found that it can take as much as 24 hours before things get back to normal. And, being that we needed to get back up to Carson City, I just wrapped things up and called it a day.
Yesterday, I started up the Gladiator and surprisingly, things were a bit better. Right off the bat, there was no weird pulsating sound coming from the subwoofer, the Infotainment system fired right up, no heater was on and I even had a rear back up cam again. Once on the road, a few things acted up again like the blind spot being disabled and the radio only kind of worked, steering wheel radio controls didn't work either and none of the center stack controls worked but at least, the Jeep drove and without other issues.
Now, here's the crazy part. The longer I drove, the more things came back to life - the more things became normal again. After about an hour or so, my radio worked, my climate controls worked, I no longer was getting blind spot errors or anything. Really weird stuff. However, when ever I stopped for gas or the like, a couple of things would act up again but just for a moment and each time, it was less and less. The only thing that's still not right is the right rear tail light is out error and that was the very first thing we saw when all this started. From about half way home on, I could hardly tell that we ever had a problem at all. Totally crazy!
I should note that I did talk to a friend who would be in the know and found that the can hub can crack at the circuit board and cause a lot of what we were seeing.
This is something I plan on replacing and with the hopes it will fix things but... only after I fix yet another problem

Value on that thing has tanked. I’ll give you $5,000 now since it’s a lemon.

Yes, intermittently some functions did not work. For instance, the HVAC and heated seats would not turn on. Then after the Jeep sat for a while, everything would be fine.
Okay, now we're talking. That's EXACTLY what we were seeing only, we have about 70k miles on the odometer so I don't think this will be a warranty fix LOL. Guess I know what I'll need to be ordering up. Thanks for the help!!

Well, glad to hear there has been a change in the right direction and things are clearing up. Still extremely weird. Gotta love computers. Imagine if you had a 4XE 
LOL - tell me about it! While I love the creature comforts, all the electronics and all that can go wrong with them leave me feeling a little uneasy.Well, glad to hear there has been a change in the right direction and things are clearing up.

@wayoflife The BCM is behind the kick panel on the passenger side. Next to the disconnect harness for the door

Awesome, thanks! I have not given that one a look
Thanks to this comment that piginajeep made on the battery replacement thread...
I should note that I do believe that part of the problem I was having is that my Infotainment system has been trying to do an update but every time it started to wig out, it'd get interrupted and that kind of made things worse. Whether or not Tazer was causing this, I don't know but I am cautiously crossing my fingers that things are better now.
I decided to give it a try as well, removed my Tazer, updated it, reinstalled it and... things are actually looking a LOT better!! In fact, I'm almost afraid to get too excited because I really didn't think it was the problem.

when my infotainment unit kept trying to do the update, it screwed things up and took at least 6 attempts of failed updates before it finally quit trying to do updates.
Luckily it did not brick the unit as I was told by Jeep cares is a possibility or they were trying to scare me into taking it to the dealer for the update at a cost of $150 (not covered even though it's their crappy Uconnect update)
I don't think the update ever succeeded as the version numbers didn't change, it just quit trying to update after several fails and forced reboots.

Great news, it’s a start. It kinda makes sense, the tazer is basically changing a line code in the Jeep, if it’s trying to boot and keeps going out of sequence due to the tazer it won’t update.
My thought anyways, and mine is worked all day today.
Yeah, makes sense for sure especially with all the updates that it kept wanting to do. I kind of wonder if the roof rack I have wasn't helping anything as it tends to block radio signa too. The only thing I don't understand is what caused everything to go nuts in the first place. I replaced both batteries back in August and never had a single problem. I only started seeing all the craziness after wheeling hard in the desert a few weeks back. As in, I'm not even 100% sure sure the problem is actually fixed.
