How to Replace the Speedometer Cluster in a 2004 Chevy Trailblazer

Chevrolet introduced the Trailblazer midsize SUV in 2002 and produced it through 2009. GMC and Oldsmobile sold versions of the Trailblazer, named the Envoy and Bravada, respectively. The 2004 Trailblazer was powered by a 4.2-liter in-line six-cylinder or a 5.3-liter V-8 engine mated to a four-speed automatic transmission. Two- or four-wheel-drive was also available. The speedometer -- or instrument -- cluster, is easier to remove than on many vehicles and a minimum of disassembly is required, making this a good job for the DIY mechanic.

Instructions

1

Park the Trailblazer on a level surface and set the parking brake.

2

Remove the screws from the left sound insulator panel under the dash with a Phillips screwdriver. Disengage the clip and remove the panel. Remove the screws from the left knee bolster the panel above the sound insulator with a Phillips screwdriver. Disengage the clips and remove the panel.

3

Remove the screws from the instrument panel bezel with a Phillips screwdriver. Remove the bezel. Remove the screws from the instrument cluster. Pull the cluster back far enough to disconnect the electrical connectors and remove the cluster.

4

Mount the cluster on the dash and reconnect the electrical connectors. Install and tighten the screws. Mount the cluster bezel and install and tighten the screws. Install the knee bolster, engage the clips, install and tighten the screws. Install the sound panel, engage the clips, install and tighten the screws.
