Dang, I feel for you. Unfortunately you are in that sub group where it appears that replacing the sensor doesn't solve the problem. I've read where others have had loose or pinched harnesses, bad switches, etc... You may have to suck it up and let the dealer do the debugging and then when it is all fixed, pot the sensors and move forward. Personally that's what I would do in your situation.Thanks for your input on this issue. I know you’ve been a valuable resource for many of us through your posting. My service warnings and chimes and off road pages originally indicated that both rear and front lockers were engaged while driving at 65 mph in 2H. I ordered the Z-locker and installed it in the rear harness. It did not solve the problem. So I ordered another for the front. Again. No luck. Still chimes and warnings. Ugh. Having thrown my money down that hole I am not sure what else I can do at this point other than play the dealer waiting game and get a new rear installed sometime in February and immediately pot the sensor upon picking up of the jeep and hoping that it’ll work at that point. But I’m not confident at all that’ll do it. I thought about ordering a new complete wiring harness and than using those with Z-lockers I have but hated to throw more pocket money away. Sooo. Perhaps than the question I need to ask is what specific parts / numbers do I need to order so I can fix the damn thing on my own and be done with it. I am not a total newb at wrenching as long as I have a bit of guidance. Sorry for this longer post / rant but I certainly do love my Jeep..... but my Super Duper Sting Gray Rubicon Wrangler needs fixing and it sure bugs me that I’m feeling “stuck without recovery gear”
Side note: Do you have a Tazer installed? If you do I HIGHLY recommend you take it out while you are dealing with this issue. One thing I don't like about the Tazer is it allows you to engage the lockers while you are in 2H. Couple that with a system in the Jeep that is flaking out and you will get those lockers engaged when you don't want. I'm saying this from experience.
Feel free to reach out to @chevymitchell or I in a PM if we can help. Shawn is WAY more knowledgeable than I am but I am better looking.
