Help needed guage lights out

[AlanSRT4]

The head lights still work but when they are on I get no dash lights at all the hvac nor speedo light up at all. And yes I played with the dimmer switch to make sure that it was in a postion where they should work and nothing. Any idea where and what to check. I checked the fuses under the hood and they were all good. Also I noticed that if the lights are on and the door is open with no keys in it does not give me that warning buzzer either now.

Thanks for any help you can give.
