The snow plow in my truck is not moving after the cool weather we hade last night in NJ. The motor still runing but my plow is not going up,left or rigth, but is going down

Are we talking about a snow plow that is connected to the front of a vehicle? I would check to see if there was an obstruction in the hoses that operate the right to left movement. Also see it there is something jammed in the plow limiting or restricting its movement.

transmission belt is worn out or slipped off pulley somewhere service drive belt then try it out

Hydraulic fluid doesn't really freeze. When it does, we wouldn't be around to see it. You need to go threw electrical. Go to there web site and see if you can get a diagram for it. Old systems are fairly easy to go threw. Newer ones have PC boards. Older ones, the stick/switches go bad first. But it always wise to loosen, then tighten the nuts that hold wires first. Corrosion sets in because it isn't used for so long.

Probably a bad hydraulic seal, or low fluid ? Typically seals go bad then pressure is lost to move properly. ...

I think you have a problem with the plow motor grounding out. when you raise or turn plow in either direction you have to run the plow motor which is grounded out. ( as in hooking the ground and positive together directly ) the plow is on a gravity drop when you let it down by the weight itself and does not require the motor for the plow to operate. It's your plow motor or the positive feed to selonoids.

snow plows use alot of juice check state of battery if battery good check altnernator output may need to go with higher amp alternator or add a second battery

first thing to do is clean all connections leading to plow power and grounds (all of them ) and make sure there tight clean battery cables as well

next thing i would do is have battery load tested as this is probley the main cause as alternaotr working so hard to keep up it takeing all power from motor

if battery test out ok replace alternator with higher amp alternator

if still have problem after all that add a second battery to truck

the coil or the timing is out

e 60 snow plow we try to move it up an down to the left it goes to right any where you try to move it

My western snow plow will not go up or left or right with joystick. I can use a screw driver and make contact on the silanoid and then move the cables with the joy stick and then it will work. I have relaced selinoid and contacts. any ideas? Stomped

un bolt the motor from the base, the pickup is just tin, they rot off and fall into the base. you may have valves stuck too, but if nothings moving and pumps running, it should labor BADLY
