rear door auto lock issue
 

Ok, so I have an issue with my rear drivers side door exterior handle. It has been this way since I purchased the car. The handle seems to not close all the way... almost like it is binding, but I can then push the handle completely in with no problem.
Now that wouldnt be a big deal except if I dont push it all the way in and it is left out, it seems to not lock. Yes it is latched but when the grab handle is left out the 1/2 inch or what it may be when I close it without puching it in... the lock on that door wont work. If I push the handle in, everything is fine and it locks.
Other then the exterior handle sticking out a 1/2 inch, then if I push it in and then it will allow the door to lock... everything else about the door and the operation of it seems normal.
Any ideas?
Thanks
