2006 hhr radio light
 

Just got my hhr. The radio lights worked at first now they don't. All the other lights on the radio work but no radio display lights.and every time I unlock the door with the key the alarm goes off
Anyone have any idea how to fix these things

Don't lock with the remote then unlock with the key.
Turn the dimmer knob back to the right.

If turning the dimmer to "Full Bright" as Don suggested doesn't produce results, then you may have a failing head unit display.
