    Hey guy one of my western unimount straight blades are slowly lowering, while it's raised up I'm thinking it's the valves or could it be something electrical .

    As shown in the diagrams provided by DieselSS you can see that the S1 valve is the only thing that will allow the blade to leak down. Sometimes you can pull them out, put power to them (to unseat the valve) and then blow out any debris that is caught on the seat. If that doesn't work just replace it. There are three valves under the cover, the front one is the S1. Be sure to have the plow lowered when you pull it to relies the pressure.
