    The plow is raised all the way. Plow will turn left and right but will not go down.

    Any ideas?

    Thanks

    bad connection in the 9 pin harness is likely. angle it to the passenger side, get out and unplug it, then plug back in and move the plug around in the socket.

    If the power is disconnected from the plow shouldn't it just lower automatically? If it doesn't would you think it is the nut tightened to tight that is keeping it up?

    The first two posts beat me to it. Yeah, put it in float and go out and wiggle the plug making sure to steer clear of the plow. It's probably a bad connection or a broken tab in the control harness, probably plowside.

    So I angled the plow to the passenger side and unplugged it, wiggled it, cleaned it and still nothing. When I push up on the joystick and then down I can hear it click once though.

    Still not sure

    Did you do this while the controller was in float?

    you need to verify if the s1 2 way valve is shifting. pull the cover off and see if the white with yellow wire is getting power. if it is, you have to see if the valve is shifting by taking it out. put a jack under the plow first, when you pull theat valve out it will come down.

    I second Got-H2o. Make sure that when you wiggle the plow to truck connector the controller is in float.

    Thanks for all the input guys. I ended up just unscrewing the quill to push down the plow by hand. I guess there was just to much pressure built up or something. The plow had not been run in two years so you never know what can happen in that time frame.

    Thanks again guys
