DIY, remove the rear door panel on the driver’s side of your Chevrolet Trailblazer, the model produced between the years 2002 and 2009. In order to do it, you will require a small flat blade screwdriver and a 7 mm socket wrench. You should be able to remove the door panel in less than 15 minutes, if you follow the simple steps below.
In the beginning, you can open the rear door, on the driver’s side (the repair is similar on the passenger’s side also) and start by prying out a small plastic cover located inside the big door handle, as you can see in the picture below. By removing it, you will come across two 7 mm bolts, that can be easily removed with an appropriate socket wrench.
Now you can point your attention towards the small door handle, where you will have to pry the bezel around it, using the tip of a flat blade screwdriver. On the door handle you will see little slots (as shown below), where you can insert the screwdriver, push and then pull out. The last step before detaching the door panel will be prying out the window switch. You can do it with the same flat headed screwdriver. Don’t forget to unplug its electrical harness too.
Once you have all these retainers out, you can work your fingers behind the door panel and pull it out. It should come out without much effort and after you make the desired repairs you can reinstall it back on the door, reversing the steps above. This is all you have to do, in order to remove and replace the rear door panel on your Chevy Trailblazer, made between 2002 and 2009.
