I have a 2008 silverado with the bose speakers. At times While driving if I hit the smallest of rough place in road the stereo and chimes stop working. Radio is still on but none of the controls will work and no sound. I can go to under hood fuse panel and pull fuse 42 and reinstall and it's fine til next pothole. If I don' pull and reinstall fuse the battery is drained by morning. Any suggestions?
