I have a 2001 Super Crew and recently noticed that when the antenna moves (even in the wind), the radio reception breaks. At first I thought it was merely a problem of a loose antenna, but it didn't stop after tightening it. Is the cable and fender mount accessible behind the mud cover inside the the passenger wheel well? I can see it entering the underside of the fender with the hood open, it is just to small a space to get my hand in to check out the underside of the plastic mount.
Any suggestions or ideas would be greatly appreciated. I really don't want to have to tear into the dash if I don't have to.
