    All right I am new at this so I am hoping my problem is an easy fix. The plow is a 7.5" fisher electic-hydraulic. The up/down adjust is working fine but the left right isn't, I can hear the pump working and the plow even shakes a little when I try to move it left and right but it won't angle. Any ideas??

    Put your blade against a good size tree and give it a little nug with the truck as you angle it from your control. The pistons can get a little sticky sitting over the summer.

    It's probably the connection at the grille. Disconnect each one and inspect the prongs visually for missing, bent, or corroded connectors. Hook back up and make sure they are firmly seated. Try them again. Look for broken or corroded connection at the battery or isolation module.

    I just went through exactly the same thing a week ago.

    I'm with Dave at Bolts on this one. If your connections are correct do as he suggests. I had this problem every year with my Diamond plow.

    I don't know Fishers, but a Western will do that if you get a piece of debris (piece of o-ring, seal, worn metal) stuck in one of the spools in the valve body. If Bolts suggestion works but it keeps happening, it could be the spool valve that controls the angling. You may want to have this done if you don't feel qualified to work on hydraulics. The source of the debris should be determined and fixed also, if that's what it is. If I'm wrong and Fishers don't have the same type of system, then....never mind.
