ok so I have MM2 fleetflex 7.5" on a jeep wrangler. About every 4-5 times I go to raise the plow it doesn't come up. It tries to, I can hear the motor and pump turn on while i'm holding the raise button down. I can see it moving up very slowly like something is holding it from going up. If I continue to let off and push on the raise button it eventually goes right up like normal. While i'm holding the raise button down and its creeping up ever so slightly it has a sound the same as when if you raise it all the way up and continue to hold the button. I have changed the fluid and replaced the raise solenoid and coil. Made no difference. If I had to guess its somewhere in the hydraulic system because as I said the motor and pump come on every time no problem when I hit the raise button.
