    I just put on a mm1 with the 3 plug harness on my 2002 ford f150. It worked great the other day and know i went to put in on tonight and it is very slow. It worked great when i first hooked up to it the it slowely slowes down, Also when i put the blade down, The piton wont go all the way down, Even with my full body weight on it. Any Ideas.

    did you do anything to your truck in the meantime??? did you change something?? I would start with connections!!!!! good gnds truckside and plow side. as far as lift ram,,make sure the controller goes into float mode. if it is,,then i would suspect wiring issues, then maybe fluid issues.
