could repairing my blower motor and regulator, short out my radio? on 2006 Mercedes-Benz SLK280

my AC wasn't working, had it fixed, and now the radio doesn't work. is that coincidence, or just bad timing?

Could be coincidence , or they might have missed plugging something in , or blown a fuse while in there? Bring it back!! asking won't hurt , and you'll learn a lot about the shop , by how they deal with it(as long as you don't go in there screaming bloody murder and blaming them , before the whole story is known , ......if you know what I mean. Good luck , hope it's just something goofy they missed (it happens!).
thanks...much appreciated!
