    Hey. I have an 02 F250 with a 2 plug MM1. Was workin fine when I got all ready for this storm. Now that we actually got snow, I went to use the truck and the plow goes up but it will not go down and it wont angle right or left. From what ive read it seems to be a valve issue. I just wanted to see if anyone had any suggestions as to what it could be. Thank you guys. Hope everyone is having good luck with this storm.

    Start with test lighting the coils while you are operating the plow per the proper function

    did you change the oil? check the oil see if the filter is clogged or the bottom of the tank could have water in it and frozen on the bottom.
