I just bought a used 2014 Wrangler Unlimited with 59k miles. A day after I got it home, I realized that the locks were not locking or unlocking. After some research, we checked the M38 fuse- it was blown. Got new fuse, put it in- now doors will unlock but will NOT lock (with the door or with the key fob)....all of the other features usually tied to this are working- horn, wipers (front and back), etc. Doors are also not auto locking when I exceed 15mph.
Going to call the dealership tomorrow, but would much rather find a solution on my own.
