I have a weird problem. On my 2015 Ram Laramie all of the sudden my doors will not lock or unlock with the FOB or the button on the door handle, or the switch on the inside. I was at a gas station coming home from a snowmobile trip, Locked the truck to go in. When i came out the FOB would not unlock the doors, Lights flashed but heard no actuator on any of the doors, tailgate or the RamBox, I had to used the key to get in. Tried the door lock button on the inside, does not work on the driver or the passenger doors. Everything else works just fine. Tried the button on the door, that does not work, neither does the unlock handle feature. Replaced the batteries in the FOB no difference. The remote starts works just fine so i know i have a connection. Is there a fuse or module that is specific to operating the locks on the tailgate, Rambox and doors.
