Transfer case shifting 4WD to $WLock on its own

We have inspection as well, I take it to my regular mechanic so maybe he just ignores it. In NJ the inspections are done at a state run facility and they might not be as friendly. I know any sensor alerts will keep it from passing inspection, but I have not had any trouble with the 4WD light.

Yeah, probably. I never switch out of AWD, so wasn't sure if it was necessary.....but suppose it wouldn't hurt.

When I got mine back in 2014, I went ahead and switched out all fluids to Amsoil. So I went ahead and did the transfer case as well. Uses ATF+4.

So I replaced the transfer case motor today. Although I did manage to do it without removing the drive shaft, I did have to remove the transmission mount and splash shield for the motor. I tired just removing the bolts that hold the trans mount to the trans and lifting the trans to slide out the shield, but with all the curves in it which wrap around the motor, this was impossible. I had to remove the bolts that hold the trans mount to the cross member as well to pull the mount out first, then slide the shield over to drop the motor.
Bad news is that for some reason the plug for the motor just didn't seem to want to plug in all the way on the new motor. Therefore I am still getting a "SVC 4WD" light as I suspect it is not making full contact. Not sure what is going on here. Looks like the plug on the new motor is slightly longer and won't allow it to seat fully. With the Texas heat and having to work in a gravel driveway, I think I'm done with it for a while.

I have the 07 aspen with AWD, Hi and Lo. So on Sunday I went somewhere and noticed the truck is in 4x4 lock but no lights on. Tried turning the switch to 4high lock and 4 low lock and nothing. Monday morning I started the truck and I had 4x4 lights and everything switched normally. Tuesday morning no lights again and no 4x4 again. Decided to get a new transfer case motor and just had a local mechanic put it in. I still have no lights so maybe it wasn't the transfer case motor. Although the old motor has this slopping around sound in there. What will be the next to check.....the front control module maybe? Any help would be appreciated.

What a coincidence. Mine has started doing this as well. Was going to ask about it myself.
I started hearing an odd sound when vehicle wasn't even running. Just parked and locked up. Sounded like a metal on metal slicing sound and then a "thunk". Didn't know what it was at first. Then I turned the key on (engine off) and rotated the dial and realized it was the transfer case. I also started seeing the "SVC 4WD" light on the dash intermittently while driving.
Today while slowing down in a parking lot, it jumped in to 4 Low. I personally think it may be the dash switch as I would rotate through the settings and hit the dash below it and it would stop for a while. I'm going to try and disconnect it first to verify.

It's probably going to be the transfer case motor. This has been discussed in multiple threads and across multiple forums I'm on. Seems to be a common issue for the motor. I did replace mine, but I went aftermarket and the plug seems to be longer and won't connect to harness properly so it's still not working as designed. However, it is no longer trying to switch on it's own so I've left it as is for now. I don't have a garage to work in so it may be like this for a while. I need to pull it back out and try to shave the plug down a little. Others have posted that replacing motor has resolved their issue. So I would start there.
