Just recently a friend of mine noticed that my LR door was not opening but still worked fine from the outside handle. Triple checked that the child lock was off and that the door was unlocking just like the others but it still does not open from the inside handle.. It feels almost like the handle is slipping once it reaches the point where all the other doors pop open. Is this a common problem? Thanks in advance.

 

Pop the door panel off and make sure the cable to the door handle is in its cradle and not broken. That is my guess why the handle inside doesn't operate the way it should.
