How to Remove the Headliner in a Chevy TrailBlazerby Russell Wood
The Chevrolet TrailBlazer has been popular since its introduction as the heir apparent to the S-10 Blazer line. Modifications to the SUV include roof-mounted monitors and custom suede headliners. To do these modifications, you must remove the headliner from the vehicle, which can be an awkward process. It should take about an hour to do.
Pull off the four plastic caps that cover the top of the seat belts. This will reveal the bolt underneath them that holds each seat belt in place.
Unbolt the seat belts from the pillars, using the 3/8-inch ratchet and sockets. Then pull off the tops of the seat belts, and place them to the sides.
Remove the dome lights, using the flat-head screwdriver to pop off the covers and pull out the lights. Unplug the harnesses that clip into the rear of the dome lights.
Use the Phillips screwdriver to unbolt the roof console, if your TrailBlazer is equipped with one. Unplug the wiring from the console.
Unscrew the visors and visor clips from the roof, using the 3/8-inch ratchet and Torx-head sockets.
Pull back the plastic pillar trim pieces with your hands. Start at the front of the vehicle and work your way backward, gently applying force to the clips and pulling the panel back. They don't need to be removed all the way, just most of the way to give the headliner room to move.
Pull down the rubber molding on the inside of the doors and hatch. You can push these back into place when done.
Pop the hatch, and pull the headliner out of the vehicle from that spot. It's easiest to do a straight run right out of the back of the vehicle.
Reassemble in the reverse order of disassembly.
