Hi , I came back from a vacation and found the front lights and the horn did not work. I found a fuse blown and replaced it and the front lights worked. At the point I got on the phone and called Andersen to look that the unit to find out why the horn did not work. When I got off the phone I found my warehouse guy on the forklift and I asked him "What are you doing." He said "I was just moving the plugs." Now that he did this I get the code 2B. Then he said "How do you know which way the plugs go in?". The unit doesn't move. Anderson trouble shooted the unit and found a fuse blown and replaced it and the horn now works but said the VM is bad and need to be replaced and will cost $7000. Can anyone help me please.
