Today my radio worked in the morning just fine. No problems whatsoever. After work around 3pm i started the truck and no radio. Nothing, no sound, no clock, nothing!! The headunit lights work inside as do all the other dash lights. I cannot figure it out. Its so strange. Can anyone give me any tips/hints/pointers to why or how this happened?

Also, why does the AM channels get electrical interference? When the signal is on i hear the clicking in the speakers, same for the wipers.
