Your 2003 Chevrolet trailblazer radio probably cut though because of a loose or corroded ground wire. The positive wire may also be loose.
The rear blower motor resistor location for a 2003 Chevy Trailblazer Ext LT is beneath the passenger side of the dash.
Because there is a known issue with the brake lamps on the 2003 Trailblazer. I own a 2003 Trailblazer and had to take it in for service on a recall due to the issue. Take it to your Chevy dealer and have them check the VIN to see if the recall was ever done.
