2 plugs or 3 at the grill? What are you running for a controller, Joystick, or hand held?

The controller might be bad or the one of the valves in the pump could be bad
Or solenoid might be going

You’re looking at the possibility of a few things. First and easiest is the controller, do you have a backup, or a friend nearby with a controller that you can try out? If not, go through the steps below as a proscess of elimination.

Second is the wires on the solenoid, make sure all connections are tight on the solenoid. Track all the wiring under the hood (paying close attention to the control harness itself obviously) to check for broken, pinched or chaffed wiring.

Third, clean out the grill connectors with brake cleaner, and inspect the pins, sockets, and the wiring leading into the connectors themselves. re grease with dielectric grease afterwards.

Fourth, remove the cover off the manifold to expose the coils & cartridge valves. Inspect the wiring, and make sure they are snuggly connected to their respected spade terminals. You'll need a helper for this next step...Have someone run through the operations (up, down, left, right...) using the controller (truck, and controller on), use a screwdriver or other metal object, check for magnetism at each coil from operation to operation.

If there is still no resolution, you’ll need to drain the fluid once again. Remove the coils, and then the cartridge valves. Blow the bores out with brake cleaner and air. Take the valves and clean them up. Check the orings for damage or wear. Push in on the end of the valves with a pointy object (test light probe is ideal for this). They should smoothly go in, and when released, should run back out by themselves. If not, scrub with an old toothbrush or stiff brush or replace as needed. If everything checks out, bench test them, put the coil on the valves, and then supply 12v & ground to each setup, make sure they spool in and out. If they worked fine manually, but not with power, then the coils are junk, replace as needed.

This sounds like contamination to me…water still in the system (condensation), blockage from debris..…run through the steps and report back with any questions. If it were me, I might skip right to the pump side, but you might as well check out the less involved things first.

When you changed out the fluid, and filter, did you remove the pump from the bottom of the reservoir, and did you clean the reservoir?

You should’ve stated the highlighted bit of information first and foremost...it's all in the details. Run through the post and you'll find it. Play close attention to the s3 valve when you get there...if you get there. It's the one on the bottom.

The absence of corrosion doesn't clear it. I don't think your controller is the issue, but don't dismiss it just yet.

If it's water (condensation), or debris contamination, it will move around, and block sporadically. If it's electrical, the smallest movement, vibration, or even environmental aspects can make it act sporadically. There is so many things that can effect it…I’ve seen a splintered barrel fuse cause $600 worth of unneeded parts…I’ve come to learn that you leave nothing left un turned.

Definitely possible. I wouldn't rule anything out just yet, but my money is on a grill connector, loose wire on a coil, or a problem within the manifold (coil, valve, or contamination...or a combination of all).

thank you,

Good job on cleaning out the reservoir ..believe it or not, I've seen several guys not do it. It can get nasty in there.

Solenoid s (?), the one under the hood? Or do you mean the valve & coils on the plow? No matter, if you run through my steps FULLY, you'll find the issue rather quickly. Hopefully you have a heated garage or something. It says it's 40° here...it feels more like 20°.

Happy hunting, I look forward to hearing your results.
