    The clicking he's hearing is the solenoid firing.

    Check power connection to your plow power plug with a set of testers, and report back.

    Sounds exactly like what happened when we lost a motor. Does it still go down?

    i had same problem it ended up being broken wire right at the connector. another common problem you could check is take the 7 pin plug and twist it while someone operates the fishstik. alot of times the female side of the pins could open up from inserting and removal of the plugs.

    Another possibility could be on the truck side. It's nice if you have two plows to check truck side or plow side. Wiring issues can be hard to track down especially if they are not constant or a sticky solenoid.

    motor is dead would be my guess, or the solenoid is toast but unlikely since its clicking

    If the motor is running, but there is still no movement, check power at the individual solenoids that control hydraulic flow of the pump, there are three. If you have power to all three, pull the solenoids and clean them, then test them in the coils with a 12v source for lock. If they are good, it's probably your pump that has gone bad, and not the motor.
