    fluid is full, filter is my next project however bolts holding unit to frame are frozen and screws for tank as well.. Is it ok to use a small amount of heat on these? thanks

    filter would effect all positions. Pull cover behind head gear, ypu will see 3 solonoids, 1 is L/R, 1 is lift, 1 is float. Ck wiring connections all all coils, remove each coil and pull off, clean off any rust build up on spool shaft. Tighten these back down just a little after nut has contacted coil, to not crank on. Use a test light and have some one move the controller to up, see if you have voltage, also pull off the controller wire at the grill (the one with 3 wires) and see if you get the light to illuminate when you go to lift. I'll post the color of the lift wire when I go check. Let us know how you made out. Good luck
