I have a 2001 F-250 and the auto door locks quit working. The remote and the button inside both give the same result nothing. When you push the lock button it makes a noise like its going to lock and the stem on the door moves a little but dosen't lock.
And each time you push the button it gets weaker and weaker untill it stops doing any thing for at least a min. Same result on all the doors. Any advise would be great.
I had the same problem with my 2001 f-250 the door actuators have shorted out and you need to replace them you can do it your self, just remove the door panels and unplug the old ones and replace all I had to replace were the front two doors.
