All of a sudden with the switches there is no response. With the remote, it works fine. Back window, notta, needs key.

Check tosee if switches are getting and sending power if not they may be bad, then get scanned for codes by a mechanic.

There is a door lock module at rear of truck to operate door locks. Check fuse 13 in passenger area and door lock relay in center of dash if all that stuff is good along with first reply get scanned by a mechanic auto parts scanner are unable to pick up anything other than eng/trans codes. Very few will pick up some abs codes.
