    You have a sticking valve. S2 if I am corrrect. The quickest way to free it up is to push against a wall or post or another snowplow and press the controller the way that you want it to go and pop the valve. If the plow works after you do that, you need to pull your valves out and properly clean them.

    If this is the same set up as a uni-mount. The suction sceen on the pump maybe plugged. Drain the fluid, remove the motor, pull the pump and replace the screen and o ring.

    Had the same problem with mine a few years back. Was a solenoid cartridge valve that was bad. If you click the link and look at the pic, you'll find the valves towards the lower RH of your screen. The valve that was bad on mine was the longest out of the three valves. New one was $70 and took ten minutes to install.

    If the link doesn't take you directly to the exploded pic, it's on page 8.

    I agree...probably sticking valve. But, it could be a wiring problem. I would check all the pins on the connectors, clean them, and re-grease. Could also be a bad ground wire.
