The arms are stuck up and won't come down? What kind of controls do you have? Lets just say you have std foot control, do the pedals move. If no, spool lock solenod problem. If they do, I would lean towards the aux being stuck on. Does is sound like it is laboring? What normally happens when the aux is stuck on is lift will raise, but not lower and tilt really won't work at all. If all eles fails, check the drive belt. As to the location, sitting in the machine it would be below right arm under the cab.
