The rear access door on my Trailblazer will not latch when I close it. Help.

look at the locking mechanism on the door pull the handle like you trying to open the door theres a little latch on your door locking machanism that you can pull back sometimes youll need a screw driver but it will only work if your hold the door handle as if you were trying to open the door

When you move the latch in the door, will it LOCK into the closed position, then you have to push 'open' to release the latch again? If it locks when you move it manually, then the STRICKER needs adjusting. That is the part the latch latches on to. I repeat will it LOCK in the closed position whith the door open?
