Audio Systems: 2002Trailblazer Bose radio system, garage door opener, bose radio

Question
We have a 2002 LTZ Trailblazer which the Bose radio system just appears to have died.  I have checked the fuse and have no ideal what is wrong. The vehicle is fully equiped with On Star and the only thing I did was set the built in garage door opener.  The next day when we started the vehicle the radio nor the CD would turn on.  Do you have any suggestions?

Answer
Rick,
The stereo in your trailblazer has two 12 volt power feeds, one for memory(hot at all times) and one switched from the ignition. I don't have a book of wiring diagrams for this vehicle, you may want to call the dealer and ask the service shop what two wires are for 12 power to the stereo and check them for 12 volts.
