01 dash lights wont come on

[cstm68]

i got in my truck tonight (2001 silverado z71) and as i took off i noticed that my radio wasnt lit up but it was still playing just fine and all the buttons worked, then i noticed that the guage lights wernt on. i turned the truck off and put the the key in the on possition with the e barke off, the clock on the radio was on but still no dash lights, when i turn the key to run the clock goes out too. what could be worng, a fuse? dimmer switch?

i did just replace my RF ABS wire and sensor but they worked fine after that.
