Went to use my turn signal Monday and they didn't work. Looked for the fuse when I got to work couldn't find it so called my buddy who is a Chrysler tech. He told me if the fuse was good, he thought it may be the fusebox itself. He said they had seen several that had gone bad and since I had just returned from the salt air of FL, he thought mine may be going. I jiggled the box and heard the flashers start to blink. Tuesday had the same problem, took the lid off of the box and have had the signals & flashers work all week. Anyone else had their underhood fusebox go bad? How difficult to replace? Keep in mind I'm mechanically and electrically challenged. I did however pull a Durmax towing a fifth wheel out of the sand in FL, though.
