Audio Systems: Radio in 2001 mercury sable, 2001 mercury sable, light fuse

Question
No, the repair was not done on left side of trunk - it was under the hood.  Head gaskets reworked, I think.  But when I got the car back, radio would not work. So we should check the trunk for radio fuse? Left side?  We even took car to audio place but they say we need to take to Ford dealership - I hate to pay alot of money to have it fixed...or even looked at, for that matter.

Question -
After I had repair work done to car (not audio repair), the radio will not work - I'm told that it is getting main power. The radio/ac is one unit and the a/c is working. We can not locate the fuse for the radio - Manual does not specify radio fuse.  Any suggestions?

Thanks
Kim
