OK My 2011 had a "no dash power off" issue when we got it. I had quite the post about it and what I did to find the cause. BUT what I did learn when having the center stack out was there is a module basically right behind where the screen sits that controls HVAC functions. With the convoluted way CAN/BUS runs in these cars it is possible that that module may be bad and causing the problem, IF you have access to used parts try replacing that module, but make sure it is one for the auto temp system if that is what your DJ is equipped with. This is definitely an ODD problem, I've got 3 of these cars{had 4 but sold one off recently} and never had this type of problem. GOOD LUCK and keep us posted..... and I hope all is now OK on the "other fronts" for you.

Seeing how this is such a "touchy" problem, lets back up a bit and do some further "sleuthing. Vibration was there with shaft OUT Vibration was GONE with fresh PTU lube and shaft out Shaft IN and vib. back, but at what speed? How many miles on this ride again? I'm fearing worn PTU or even play in FRONT differential carrier bearings{part of the trans.}. I've always preferred putting my "eyeballs" on a problem to try and access things than over printed word. This is quite the "quandary" to figure out, Good Luck!

Sorry to hear of more "glitches" from your DJ. I would have thought that by the year of yours this problem had been rectified on the assembly line. None of my DJ's have exhibited this problem, so I can't offer any advice to this concern. Good Luck.

As member 2late4u posted, yes areas to check. But to your further inquiry, YES depending on failure point IS on the board.

Most likely the circuit board in the radio is going bad{cracked solder points}. For your year the radio unit is plug and play for same type replacement, should be lots of radio units{not the screen}available at wrecking yards. Not hard to take the center dash stack apart to get to the radio unit, lots of youtube videos that can help you along about this task. There is a CHANCE also that the HVAC/radio control panel may be going bad also, Good Luck and WELCOME TO THE FORUM!

Glad you have made major progress ! A lot of work and parts, but now you can start ENJOYING the ride again instead of being ANNOYED.

Well my '14 sxt is now gone. My friend needed a decent ready to roll vehicle for his stepdaughter. She blew the motor on her later mosel Jetta turbo and can't find a good used motor for it. So Thursday I drove it over to his shop and made the transaction, a little "dickering" on total price{cash& used parts} and the deal is done. I hope she takes better care of this DJ than her Jetta. Friday I went to DMV and turned in the plates and registered the wheelchair van and put the plates on it so my friend can road test it to make sure all is good after his initial servicing to it. I hope to have it in MY driveway by the 16th. My friend has been totally swamped with work lately.

Also, don't forget to check the condition of the pigtail connector to the Battery Sensor. Small wires and subject to the same corrosion effetcts as the battery terminals themselves.

IF your front brake calipers use ONE piston in each caliper, order the smaller rotors IF your front brake calipers use TWO pistons in each caliper, order the larger rotors rockauto.com is pretty reliable for explaining the differences on how to determine what you need, I use them A LOT for my parts needs.

We have VERY SIMILAR backgrounds!!! Actually the viscous coupler is NOT spinning with driveshaft out, BUT the differential IS spinning on the spider gears and ring gear/and bearings. Just like the rear end of any RWD vehicle and why I suggested checking the rear diff gear lube. As I stated, I can't and don't hit the speeds you can{legally}, but I have to question that your vibration MAY be wear in the rear differential. What did the drain plug magnet show like when you "changed out" the diff. fluid? The front PTO also has gear lube and is rather difficult to check/fill. but low on lube or worn can cuase vibration through front floor AND steering. NOTE, both units I would NOT put on a list to just replace with new/reman. units....it would cost more than the car is probably worth. Thanks for clarifying things, I think all here now have a much better understanding of the situation. Keep us posted!

Only ONE of my 4 has the 8.4" screen and is a '13 model with no problems. IF you have already gone on the settings page and worked with the display brightness settings, then i'm sorry to say I have no suggestion for you Good Luck and let us know if you find a cure for this concern.

Just so I understand better.... you only get this vibration at speeds above 75mph? A bad rim or tire would show up around 50 - 65mph. Thanks to my area, I dare not push speeds beyond 70mph and only in a short passing situation. Is the onset of this vibration felt more thru the steering wheel or from the floor/rear area? AND just how "severe" is this vibration? Is it an annoyance or "OMG" I have to slow down till it goes away????

Welcome to the forum. Unfortunately you did not give much background info of any thing you noticed when this happened for members here to "go on". Do the heat/ventilation controls work thru the display screen? and is this the 4" or 8" screen infotainment screen with auto temp controller? Are you able to do any investigating/ disassembly /repairs yourself or reliant on a shop/dealer to do your maint. work?

Well it's been roughly 3 weeks now. The wheelchair van is paid for and after a full week of trying to get insurance for it{successfully}, I will be getting the plates for it this week when I can come up with the $$ for title/reg./plates. Had a heck of a time on insurance as the Dodge vin was listed as an incomplete vehicle and would not come up for a normal vehicle. Insurance Co. data bases have a special section for such conversion vehicles that it seems most "representatives" do not know about. Finally got it done and at a good price, even cheaper than any of my 3 other cars for same coverage! The '14 DJ is temporarily staying with me, till my friend decides what he wants to do with it. Higher mileage and some minor body rust but mechanically top notch

You may be on to something here! I took the OP's word on multiple balancings being done and should have revealed a bad rim situation IF the person doing the task watched the tire AND wheel spin. One would not expect to see a bad aluminum rim unless a very noticeable bend from say a curb hit or severe pothole. I did countless tire changes and balances in my day and always watched how the tire and rim for "wobbling" as they spun in the balancer. Also an unusual amount of weight being needed to bring a tire "into balance" should be another "tip off" to a tire or rim problem. My standard was anything over 4 ounces on a passenger car tire was cause for further investigation. My apologies to our metric standard members for not giving the metric equivalent, but I think you will understand the "gist" of my posting.
