Re: AC quit working on 2014 Jeep GC
As I mentioned, we're traveling so took it to the local Jeep dealer here in Tupelo. It's a small dealership but I arrived at 0730 and they went to work and worked on it until 1330. They eliminated ground straps and the water problem under the dash. They spoke to Chrysler engineering and they recommended the wiring bus. The mechanic was working on troubleshooting the bus when it self fixed. He messed with everything in the vicinity where he was working but could not again cause the problem. They told me they did not consider the problem "fixed" but could not troubleshoot without the problem in place.
The trouble codes: BCM: U0011-00, U0147-00; HMS: U0011-00, U0147-00; ICS: U0011, U00184; MSM: U0016; AMP: U0011, U0184; RAD20: U0010-00, U0011-00, U0140-00; EDM: U0011, U0010, U0141; HVAC: U0184; PLGM: U0010.
They left these trouble codes in place to assist the next troubleshooter. They had a similar wiring harness problem on a Chrysler 300 that eventually required them to change out the wiring bus. Hopefully that won't be necessary in our case.
We are going to continue the trip and hope and pray it will hold together until we get it home so we can lay it in the hands of our home based dealer. We will then be able to return the car to that dealership until they fix it or explore other alternatives if necessary.
