    I am at a loss any suggetions???

    Plow executes all opertaions normally but will not stay up. Creeps down slowly.

    Had this problem last year and thought it was fixed but no luck.

    Replaced lift cylinder.
    Replaced S3 valve
    Replaved S4 valve

    Today I replaced S4 and plow did not lower, i thought it was fixed. After driving for a bit and going over a few bumps now plow lowers by itself.

    Anyone else ever have a problem like this? My next step is pressure relief valve.

    Hope everyone made it through the blizzard ok.
