If you are talking about rear cargo type doors and it sounds like you are, you will need to remove the door trim to access and inspect the latch assembly and the linkage to it. It is a little difficult to do with the door in the closed position, but if you will look at the center part of the trim that is surrounded by all the plastic, if you work at it a little, you can actually pull the center part out without removing the plastic part first. Loosen what screws you can and pry the plastic up so you can get a good hold of the center insert and it will pull out from under the plastic. It only has 4 small screws that hold it in place and they will tear through the material and do almost no damage and they will be covered by the plastic trim when put back together. Also sending R&R instructions for the latch. It may have become unhooked from the linkage. Good luck with it and yell if you need me. Thanks

Dutch door style, 2 swing out and the one that swings up has the problem? Is it this style?
Hi Ken, Sorry once again you have a similar problem. Getting to the failed part. The trim around the back glass needs to come off and being closed makes it difficult. I don't have one here to look at so can't be sure if you will be able to remove it or get it lose enough for what we need without doing damage to it or not. Once again, a call you will need to make. But if you can't get if off, maybe you can get it lose enough to be able to work with. The latch could also have linkage that has come unhooked from the center pivot or actuator. (big problem on that design) I am sending instructions from GM for trim and latch removal, but keep in mind that they do the job when everything works and make no provisions for problems like you are having with the truck. So, try to get it opened up enough to see what is working and what isn't. If it's linkage related, once it is fixed you may want to safety wire the linkage retainers so it can't come apart again. If the rod is still connected to the latch end you may be able to just pull on the rod with a pair of pliers, once you can access the rod and open it that way to get the repairs done. I would really be surprised if the latch itself has failed. Have not yet seen one do that, but anything is possible, I guess. Take a look at the following diagrams and see if you can get to it by working with them. Maybe a good idea to print a copy, just in case. If you have a problem, just drop another note here and the system will notify me and I will get back to you as soon as I can. Good luck with it and let me know how you progress. ThanksRemoval Procedure
Important: Install the new retainers whenever the control rods are removed.
