    When I hit my hand held controller, the plow goes up, comes down, right, left then all of a sudden it squeals loudly, the motor moves so I can tell its working but the plow doesn't move, if I keep hitting the button sometimes it will suddenly work fine, any ideas, driving me crazy!

    Sounds like you might have some ice build up or a bad solenoid......might try taking your controller to the dealer......they can bench test it to make sure its not messed up.

    Should I pull the solenoid and check it, could it be dirty?

    You may not have to necessarily have to remove it to clean it, just depends on how much room you have to work. Maybe take some emery cloth and clean the studs.....smear some dielectric grease on the terminals.

    Does the motor sound like its under a load when you run a function and then just stop and sounds like its getting ready for take off? You might be low on fluid.......just a thought.

    I changed the fluid and I filled it , checked it and it was full after a few cycles, sometimes the motor screeches then it just kicks in like a little violently like something loosened up or unclogged, weird. Is this a single solenoid in the motor your not talking abt the one under the hood

    Unimount has one solenoid that control the motor and it should be locate under the hood...

    Q; when you change the fluid, did you get the air out of the system?

    have you ck the connectors??? squeels and no move can also mean no valve moving.
    look at the grill connectors, look at the 9-12 pin for a broken wire right by the housing

    I'm getting a strong reaction at the motor so I'm thinking the solenoid should be either work or no work I did not check for air how do you bleed? Will check wiring too The first thing I thought was a valve not working sounds like oil is trying to flow but is intermittent which could be stuck valve or air which were my first thoughts

    Lower the plow, push dwn ram all the way in. Then remove the ck plug on the drivers side of the housing. Remove the add plug as well. Air and fluid should escape from the ck plug when done draining add fluid as necessary, install both plugs. Operate plow, up, left, right, dwn,,,a few times. Then lower ram all the way and ck fluid level again.

    I don't think its air. I think you have a wiring issue. That's just my .02. Just had a uni do that exact thing

    The way I would remove the air from the system would be manually. I would swing it from the left, and wait 30sec. Then do the same to the right. This way you are pushing the air out manually. Then I would check the fluid level once again, fill if needed. Then I would do it with the controller, left, then right, then up, then down. Once again, recheck the fluid.

    Also as Dieselss stated, check the grill harness. Make sure they are clean. You can use a pair of channel locks to close the holes a little on the female harness (then plug without the tips). Just use a slight pressure. Then put some electrical grease so it will make a good and clean contact. Also check to make sure there is no broken or bent terminals.
