    Hello. Having problems w/ my unimount and looking for some help. The last time used, the plow will raise and angle left fine, but will not drop or angle right. When trying to angle right, it angles left. Swapped trucks and controllers, same problem. Cleaned filter and changed oil. Checked and cleaned solenoids. Seem to be working properly. Replaced plow harness. Same problem. Any help will be appreciated. Thanks.

    You have a sticky valve problem. From what you describe you have two valves stuck, S1 (keeps blade from dropping) and S3 (makes plow go left) Have a look at this link. http://library.westernplows.com/westernplows/pdf/21936_121704.pdf
    On page 9 you will find a diagram showing the valve orientation. Pull the cover off, then remove the coil nuts and the coils. Then remove the valve cartraige, it comes out like a spark plug. Once out, put the coild back on and then put a nine volt battery to the coil and see if the valve transitions with a nice loud click. If not, and I expect they won't then replace them.
