HELP!!! 2004 XLT Radio turns on, CD's play but no sound?!
 

I looked around and didn't see anyone with my same problem.
Basically, I can turn the radio on, change channels and play CD's but no sound is coming out...not even static. Any ideas?
I stopped into one of the parts places and they said it may be the amp fuse/relay. I just can't seem to locate it and my owners manual is gone. Does anyone have any ideas or a picture of the pages with the fuse/relay locations?
Thanks in advance everyone.
