How to Remove a Radio From a 2007 Chevrolet Trailblazer

by Leonardo R. Grabkowski

The 2007 Chevy Trailblazer's radio screws are hidden behind the dash panel. This panel is larger than in most vehicles; it extends from the radio to above the steering wheel. Because of this, removing the Trailblazer's radio requires a bit more effort than you'll need with most other vehicles. Some Trailblazer factory-audio systems have an anti-theft feature. If you plan to re-install the radio, you'll need to bring it to a Chevrolet dealer to have it unlocked afterward.

Step 1

Set the parking brake and apply the brake pedal. Move the transmission into neutral to provide working room. Turn the engine off. Unhook the negative battery cable with your pliers.

Step 2

Remove the Phillips-head screw in the storage compartment next to the cigarette lighter. Remove the two Phillips-head screws from the speedometer case. These two screws are directly above the RPM and miles-per-hour gauge.

Step 3

Pry off the two trim caps on either side of the steering wheel. Insert a small flat-head screwdriver into the cap's bottom indentation. Pry upward gently to remove the caps. Remove the two 9/32-inch bolts from behind the caps.

Step 4

Grasp the lower-steering column and gently pull it down a few inches. Behind the column, you'll see three Phillips-head screws, two on the left and one on the right. Remove all three screws.

Step 5

Push the steering-wheel tilt lever and lower the steering wheel. Grasp the dash panel above the steering wheel. Pull it away from the dash. Move over to the right side of the panel (above the radio). Continue pulling until it's released from the dash. Unplug the two connections from behind the panel. Move the panel to the side.

Step 6

Remove the three Phillips-head screws from the radio. There are two screws on the left and one on the right. Pull the radio out. Unplug its connections.
