Looks like my cab is as bad as yours. If I was you, I would try to find a better cab. It will probably cost you more money it get another cab, but you will not be spending a ton of time trying to bring the old one back to life. When I started my project, I could not afford a new cab so I worked on this one a bit at a time. Now I can afford a new cab, but have way to much time and money into this one to change it.
