Hello,

I have a 2003 CCSB 1500HD LT truck, and the factory radio all the sudden will not make a sound. The unit is on and everything works except the fact that no sound comes out of the speaker. I tried switching inbetween radio/CD function and turning the radio off and back on again, but it didn't work. I pulled the fuse box cover on the driver side trying to find the radio fuse, but that isn't labeled. My guess is that the factory amp blew, but I wanted to see if anyone else had any ideas.
