The outside driver door handle does not open the door any longer. Am I missing a switch of some kind? Or will this require the dealer?
You’ll have to remove the inside door panel and see if the linkage has come disconnected or broken.
Open the door and check on the door itself for a child safety lock. Slide it in the opposite position and try opening the door from the inside again. I just had this problem with my car. It was locked on one of the back doors but not the other.
There is no child safety lock on front doors.
