The left rear door fails to latch close. The only way I found to keep the door closed is to operate the inside door release lever many (30-80 times) and try closing the door ever so often. It appears that the door fails to latch most often when it hasn't been used for a couple weeks. I have sprayed lubricating oil/solution into the latching mechanism several times. Each time the problem will go away for about a month and then it fails to latch again. I intend on bringing the vehicle to the dealership to see if they can do anything.
2003 Chevrolet Trailblazer EXT locks complaints

The outside back door handles do not work properly. During the warranty period, I brought the car back to the dealership where we purchased it, a few times, and they tried to convince me that the child safety locks were engaged. If the child safety locks were engaged, we would not be able to open the doors from the inside. The problem we had then and continue to have is that the outside back door handles do not work. I used to think of it as a mere nuisance until recently. This is a safety issue. I strap young children, in their car seats, into the back seats of that car. In an emergency, they might not be able to be reached quickly unless my wife or I were there to say that the door handles don't always work and you must open the front doors and reach into the back to the inside door handles to open the doors. Chevrolet has maintained that they work properly. It's kind of ironic, we strap our kids in safety seats to keep them safe, but in an emergency, we might not be able to get to them because the door handles don't work. There is a safety problem here and chevrolet needs to fix it.
