    Any ideas? All functions work but can't angle the blade straight

    sounds like the plow is not "locking" the two halves together. the two sides sound like they move but independent of each other.

    You mean when both blades are in a line you can't make it work like a straight blade? What kind of plow is this? Uni or ultra? Three plug or two (fleet flex MVP+)

    Yes. Everything else functions perfect. Can move wings independently no problem. Scoop and v is fine too

    Check all your fuses. Including the ones out on the plow.

    On the regular MVP the S5 valve is active only for straight blade angling left and right. Pull S5 and check it for damage. Also check the coil for magnetism and that the two wires r securely connected. If your controller is good this is the next step. If valve and coil r good but no magnetism then it will b an open in the wire that connects that coil to the controller for that function. Maybe controller plug pins?

    You never said if the pump motor fires up when you try to angle straight blade style. Does it sound like it is laboring of doesn't spin up at all? If it labors check valve. If motor does not spin you need a new controller or repair inside controller.

    Water had filled up the bottom cover where the solenoid was. Corroded the wire and broke it off. Cleaned it out and new wire connector and it's working fine.

    Going to have him pick up a new solenoid incase terminal is weak from corrosion

    This is a regular MVP right? Do you mean one of the valve covers, the black plastic things on the sides of the hydraulic unit? Most people call the motor relay the solenoid but that can't be what your talking about because no action would work if there was a wire corroded off of the motor relay. So was it one of the wires feeding the black magnetic coils that activate the cartridge valves? That would make sense.

    Yeah that's what it was. The cover was on the bottom of the pump. Kind of a dumb design when I think about it
