The only solid thing holding it is the bolt that secures the pull down strap. The rest is plastic push pins. Start at one end after removing the pull down strap and work your way around. The only tricky part is the top lip and it is a little finicky but not that tough.

The GMT360 platform Trailblazer from 2002-2009 never had a tailgate only a rear hatch. www.trailvoy.com
The Blazer was discontinued from production after the 2005 model year, and was replaced by the TrailBlazer. That being said, you have a short to ground somewhere in the circuit.
Open the rear hatch to access the mounting scews for the tailight assembly. Remove the scews and drop out the tailight assembly. The rest is self explanitory unless you have a fried circuit board for the taillights.
open the hatch there are two screws remove them and the tail light will come out, after that there are three more screws remove them and you can get to the bulbs to replace them
Use a set of pliers and pull the wiper arm off the stud down where it meets the hatch.
on the rear hatch of your trail blazer ,there are two (one on each side) shocks that hold the door up. thay after time have to be replaced. you can find them at any auto part store or Chevy dealer.
You have to open the rear hatch like you would to replace the reg. brake lights. Screws should be accessible once hatch is fully open.
Looking in the rear hatch of the Tahoe- it is behind the passenger side trim panel in the hatch area. You have to remove a couple of trim pieces around the tailgate, and the passenger-side rear window from the interior. Then you will see the blower motor and all of the other goodies.
Open the rear hatch and you will see the retaining screws inside the door frame.You can then drop the light out to get access to the bulbs. If no bulbs are bad then you may have a bad circuit board.
It mostly uses pop-off fasteners. There are one or two screws at the top for a cover.
