I have developed a problem with my boom/bucket operation on my 04 LS 190B. It's locked up. This started as an intermitten problem, but now its not working at all. I can move back and forth, but no boom/bucket operation. I have no indication lights telling me there is a problem. I have been reading the forum about the seat belt swithces going bad, and I do have some issues with mine, but It wont even crank up if its not right so that tells me its ok. I really need some help. I have not contacted my dealer. All they have told me in the past is bring it in. Any help would be appreciated........Mike
