the dashboard cluster could have broken. That happened to my 2004 trailblazer and I had to get it replaced
I have the exact same problem right now with a 2004 trailblazer... any discoveries?
Check fuses
There are several reasons that the inside alarms on your 2006 Chevy Trailblazer may stop working. The alarms are ran by the vehicle's electrical system so it is possible that you have a fuse that needs to be replaced if it is only the alarms that are not functioning.
They might be broken, check with a mechanic, its illegal to drive when they are broken.
Check your dimmer switch under the dash first.

If your Chevy trailblazer 2004 gauges are not working, check your fuel pump.

If all of them stopped working at once, it could be a fuse. Find the Fuse box and test the one that connects to your dash. if the fuse is bad, replace it.
The hazard and blinker lights are located behind the dashboard tray. To fix the fuse, you unfortunately had to take the dashboard out.
If you brake lights are not working on your trailblazer it could be due to a number of reasons. Your fuse could be blown, or your light may no longer work.
