    Sounds like either a bad connection in the plugs between the truck and plow or a broken wire in the plug harness.

    Clean and re grease the plugs with dielectric grease and make sure you use the cap as a retainer on the controll plug- see if that fixes it.

    With that done have someone work the control while you CAREFULLY hold the plug solidly in the truck and wiggle the wire harness (WATCH OUT FOR THE BLADE)

    These are known for wires breaking in the harness- Fisher sells a plug pigtail for replacement.

    Its your Fishstick.

    If you are using the Fishstick controller than that is your problem and it will only get worse. The printed circuit board underneath the buttons is starting to break. I know because I have gone through two.

    I have the fish stick and had the same problem but it was the wiring harness. They had to replace both sides of it, meaning the plow side and the truck side. This is the control harness and not the light harness.

    Where I went to have it diagnosed he did just what was suggested. I moved the control as he held the harness and moved it to tell if the wires were broken.

    As I was sitting there waiting for them to fix it 2 other guys came in with the exact same problem. I was told that this is a common problem with those harnesses. The replacements are made better, supposedly, so it shouldn't happen again.

    This is why I just leave my plow on. Less stress on the harness.

    harness gets moved with plow movement- everytime the headgear pushes back against the pushplates towards the truck. Not just plugging and unplugging- they should have made the harness a LOT more flexible and a couple of inchs longer.
